Hi,
A few days ago I found article about 'Which kernel use in Linux distribution' but I can't find that again, so I just started to thinking, which kernel can I use to not break the system. On kernel.org there's a LTS kernel which version is 4.19.55 or 4.14.129 but in openSUSE Leap 15.1 is 4.12.14 and as I assume the newest modules(?), drivers(?) are included as a backport right? If I'm wrong do not hesitate to correct me.
You should use the kernel that comes with the distribution you install, and is updated by the distro through its update repository -- unless you have hardware that is not supported by the normal kernel. That is the only real reason you would want another kernel. (there are some other reasons you want to look at a real-time kernel, etc.., but primarily, it is a hardware support consideration) openSuSE backports all critical security fixes to the kernel in the update repository. So whether it is 4.4 (in Leap 42.3) or 4.12 (in Leap 15.0 & 15.1), they all contain the latest critical security fixes so long as the release continues to receive updates. (they have also receive backports of the various spectre performance mitigations, etc. to a lesser degree) That said, you are free to experiment and install any kernel you want to try. the KOTD (kernel of the day) repository contains the latest kernel packaged for your release. Nothing wrong with trying any kernel you want to. Bottom line is unless you have bleeding-edge hardware (or older hardware that just had support added to the new kernel), or have some unique setup, you will not notice any difference in changing kernels, though there is always benefit in the learning exercise. -- David C.
