I picked LTS when I set up a laptop for a family member - it's an older Thinkpad (T430) and it booted fine on current but I was a bit nervous about kernel updates breaking something. my desktop is even older but I know how to fix it if anything goes wrong 
Let's talk about the LTS kernels
currently using Linux 5.6.18-155.current with celeron n3150 and there is no visible problem so far. But I tried 5.3 or sth like that before and laptop was freezing out of sudden. The most stable version for me was 4.14 on manjaro.
mojave21 the same for me. My laptop is a n3150 intel celeron and after fresh installing the system it was working flawlessly (4.9?), but after the kernel update (5.4) it freezes randomly. I installed the lts kernel and its working as it should.

Backup for the case that an update of linux-current breaks something. Like some other, I had issues with my Intel graphics in the first few releases of linux-current some months ago (gone now). I couldn't go back to linux-lts though because it did not detect my Thunderbold hardware that I use to connect to my port replicator. I'd vote for updating linux-lts to 5.4 because of broader support for modern hardware and less testing efforts for the Solus team as @DataDrake explained.
In my case 5.4/5.6 are somehow more stable than previous kernels. No issues on older laptops: Thinkpad T450 and MBP 2011 and Lenovo Y715 (at least I haven't noticed). My workstation (Ryzen/Navi) sometimes glitches just after boot/shutdown (can be just Plasma issue). I've used lts maybe once but it didn't boot (shitty hybrid graphics on MBP) 
I think decision really depends on how many users run lts because they must, not because they want. I personally don't care about lts as long as I don't have to use it as fallback. In that case only 5.4 could work.
A couple versions ago the current broke my wifi, but that's it . Now all is fine.
I'd vote for 5.6 of that's an option. I'm running it on what is essentially a 12-15 year old netbook and have had no issues with any of the distros I've tried. Solus Budgie actually runs the best on my particular hardware.
I also vote for 5.6 due to proper temperature and voltage/current reporting for Zen/Zen+/Zen2 processors.

Just to be clear, 5.6 is not an LTS kernel. https://www.kernel.org/category/releases.html
I think in the long run 5.4 is a safer bet for LTS
Whatever is your choise tkere always be kernel-hoping inside a distibution
or on distributions. The hardware combinations that is active on the market
is huge and mixed. New cpus and their chips are installed alongside with
older other hardware such as wifi adapters ,sata or nvme chips the list is
endless. That mess is not a new issue. I remember Debian had the same
at version 8 or 7 i'm not sure, where the 3.16 kernel could not support the users'
hardware who upgraded from one version to another and had used older
hardware. I bought my laptop late in 2018 when almost every distribution had
the 4.19 kernel as default, which can't run on my hardware.
HP G7 755 AMD A-9220 Radeon R4 (Stoney Ridge)
intel wifi 3168NGW (Stone Peak) rev.10
Realtek ethernet RTL8111/8168/8411
That time Solus iso shiped 4.20 kernel as default and it was the only
kernel that run on my laptop. If i had tried Solus 2 montns later with kernel 5.22 i
wouldn't had known how budgie looks like because this kernel can't boot.
In almost every week there are kernel updates to higher versions.
Is that urgently necessary?
I voted for 'I installed Solus when it was still the default kernel and haven't
switched.' If i had the option to make two choices i would had chosen the
'i want a more stable kernel experience.' as well.
On other distributions that i use i have compiled my own kernel which i can't
do on Solus.
stylste I would really appreciate it if:
- You didn't use 80 column wrapping. It makes your posts harder to read and unnecessarily long. Line-wrapping works perfectly fine here.
- You didn't "kernel-splain" to me why having multiple kernels is necessary. I am painfully aware of how different kernels versions don't mix with various hardware configs. The main reason for this poll is to better understand what I can't see, which is how people are deciding to install the LTS kernel when it hasn't been the default for years now.
stylste In almost every week there are kernel updates to higher versions.
Is that urgently necessary?
Whenever possible, yes. Most kernel releases include a dozen or so bug fixes that can affect anything from filesystems to drivers to cryptographic primitives. Getting those fixes out to people is important for stability and security.
Yes, I'm sorry
i had to pre-write this text in my text editor and copy-paste it here because of unstable internet connection earlier
this day.
DataDrake You didn't "kernel-splain" to me why having multiple kernels is necessary
It is not necessary , it is vital, in system that holds only one O.S. and receive kernel updates almost weekly ,
which is my case. It is not necessary in systems with more than O.S. installed on them , which i don't like and never
use.

There are many older posts on this forum where there is a piece of advice to people who have problems to install
LTS kernel. Does this shows something?
When one installs Solus does he knows that there are different kernels and if so can he install what he wants.If later
one install LTS kernel he does so not as a matter of choice but as a matter of need.
What i would like to have is one (1) stable kernel , i don't care how the name is , which will make my hardware operatable
always.
[Of topic
I have been using linux exclusively since 2004 and never had kernel problems until last year. That kind of problems
sometimes make me considering to switch to another O.S ]

That is a literal impossibility. Nothing in software will ever work with 100% of hardware. And even beyond that, what is being talked about here is in a way seperate from Solus and will effect ANY distro using that kernel. Even if DataDrake and the rest of the solus team had endless resources and wrote bug free code 100% of the time these issues would still remain (again, on any/all distributions using that version kernel) because they are at the kernel level and not the level of the distro itself.
You even noted this yourself in your initial comment

Annnnnd you go right back to trying to explain to me a point of view I already acknowledged and understand. I would point out that the vast majority of our users have had no issues with the linux-current kernel over the past few years. It's only a small, vocal minority that have run into problems that we didn't catch before a Friday sync. Your assertion that this is "vital" is textbook confirmation bias and I won't give into it.
stylste There are many older posts on this forum where there is a piece of advice to people who have problems to install

Yes, it shows me what I already know: having an LTS kernel is useful for allowing people to continue to use their system while we sort out regressions in the mainline kernel.
stylste When one installs Solus does he knows that there are different kernels and if so can he install what he wants.If later one install LTS kernel he does so not as a matter of choice but as a matter of need.
These polling results show the opposite. The majority of people who responded have installed linux-lts as a backup in-case of an issue with linux-current, not because they encountered one and needed to work around it.
stylste What i would like to have is one (1) stable kernel , i don't care how the name is , which will make my hardware operatable always.
And I want to end discrimination, poverty, world hunger, and to have a million dollars in my bank account when I wake up tomorrow. All of these things are more likely than a piece of software as large and complex as the Linux Kernel to be free of any bugs whatsoever. This kind of reliability has only been proven with formal verification of a fair few microkernel designs and even those don't have guarantees of any of the drivers or other software functioning perfectly.

If you are that easily swayed by buggy software, you will never find an operating system that works for you. It doesn't exist. While I agree that the 5.X series kernels have had more regressions than I would like to see, there's still an incredible amount of that code that continues to function without issue. Most of what we have seen are a few hiccups with drivers that were mostly resolved quickly or the odd breakage of bluetooth protocols and filesystems. Most of which Solus caught and fixed before the new kernel was released or within a few days of the problem being noticed, prompting an early sync to fix the problem.
Now, I've been very patient thus far in my responses to you and at this point, I would ask that unless you have further feedback about your specific experiences with the kernels that you wish to share, that you let other people take a turn responding. Otherwise, you have said your piece and I, personally, don't need to hear it repeated. Thank You.

I Understund.
I don't argue with anyone.I respect your work and your effortless contribution.
Something last from me and you will never hear from me again.
You took a step creating budgie. Take another and listen to your your users. You do not know how many
gave up after a failed first boot.
Thank you for you let use out of your effort for free.
Goodbye.
stylste I don't argue with anyone.
Except you have been arguing with me.
stylste Take another and listen to your your users.
We do. Even when they are being rude.
stylste You do not know how many gave up after a failed first boot.
I can't always fix that. I can't know what I don't know that I don't know. But when users report problems, people certainly do try to help fix them for everyone, myself included.

DataDrake You're my hero,a very good person and we know that you always made a lot of effort to keep Solus the best OS in the world, don't bother to reply to people that is rude.
I promise that in a near future you will receive a good contribution for all the love that you put in this beautiful OS. When you enable donations and publish Solus 4.2 I think that then it's going to be a really important chapter in Solus History
