The first version of Linux I ran was Ubuntu MATE. I enjoyed the Community but eventually borked my system. After that I ran Zorin OS and enjoyed it very much until I borked my system. I tried running Parrot OS but it was only a short time before.. I borked my system.
I was stuck on Fedora Gnome for a long while. I loved the experience of Gnome 3 and the intuitive design. However Fedora 28 had many simple tasks (like adding a VPN through a .opvn file) that had issues. It took me a month to figure out how to get VPNs running right. Whenever I got things working something would break.
Then I found Solus 3. I loved Budgie immediately. I loved the ease of use. I loved everything.
I couldn't install Solus on my desktop until Solus 3.999 fixed some of the UEFI issues. Once that ISO came out IIRC I migrated every device I owned away from Windows for good. My current desktop has been running stable and secure with only two small issues since March 2019.
I honestly couldn't imagine running anything but a Solus Operating System. I know for certain I would never run a Debian/Ubuntu-based distro again.. I borked them all.
If I were FORCED to choose..
Manjaro Budgie.
However I do not feel safe, secure, or at ease unless I am running Solus. Solus KDE is the only version of KDE I have tried that I felt was usable. Solus Gnome surpasses Fedora Gnome IMO in implementation. Even Solus MATE is superior to Ubuntu MATE IMO.
The only desktop environment where any other distro competes is Manjaro Budgie. I enjoy some of the python-based applets. What I like in this applets though is greatly outweighed by my distrust of the AUR (you might as well be using Windows and getting .exe files from download.com OMG!). There are many programs, such as Vivaldi, that I am only able to download through the AUR and that tarnished my overall experience because I never feel at ease using community based repos.
If Solus disappeared tomorrow I would look for another distro with Budgie. But my real preference is to have Solus installed across my devices because everything just works.
