  Unless you have super-new bleeding-edge hardware that needs a new feature
added in 5.1 that is not available in previous versions -- then 5.1 provides
absolutely no benefit. Any tweak that 5.1 provided to help with Spectre
performance mitigation, etc.. will likely be backported and in a LTS kernel.

  I have Arch (that always runs the current upstream version of the kernel,
5.1.9 currently), and Arch also provides an LTS kernel using 4.19. I have a
SuSE leap 42.3 install running the 4.4 kernel, SuSE leap 15.0/15.1 installs
with the 4.12 version, I have a Pi running Debian/jessie with the 4.9 ARM
kernel, and from a general computing/feature/functionality standpoint, it
makes no difference.

  Now if you have bleeding-edge hardware that is only supported in the latest
greatest kernel -- then yes, there is a difference, otherwise you won't know
the difference.
