If I remember correctly linux-current was fairly buggy when it was first released, and it took many point releases before they finally stopped having some regressions (one or two of those regressions were also nvidia driver related). Luckily with all the updates, I've been running linux-current without any issues for months now, but generally speaking for my Acer Aspire E5-576G laptop with hybrid graphics, I tend to experience at least one or two breakages/regressions from the kernel each year, so I have the LTS kernel as a backup that I used for about a month because the regressions don't always get fixed right away. I'm a patient person so I don't mind the wait, however, since the last couple of updates, the 4.9 kernel no longer lets me boot into a GUI, so my backup is no longer a working backup. Now I'm not too concerned at the moment since linux-current has become a very solid kernel now, but I do always have some concern when a new kernel is released that's a new major version. Having said all that, I'd be willing to test and see if the 4.14 LTS kernel is a worthy successor, but it definitely isn't an easy decision because no matter the kernel, some users will encounter problems, we just have to do our best to find and use the kernel that causes the least amount of problems for the community. I for one am glad we are having this open discussion and am hopeful we'll figure something out together.
