I’ve heard LTS kernels offer more stability, but lack the latest features. How likely is my system to break with the standard kernel?
LTS kernels aren’t more or less stable. Rather, they have been selected by the kernel maintainers to get security fixes backported to them for a certain time.
Ubuntu does the same thing for the kernels on their LTS versions (technically they usually are not LTS kernels since canonical supports them instead of kernel team)
Overall I’d suggest going with what the distro provides unless you have very new hardware, in which case a newer kernel may be required
