Depends whether you go with Tumbleweed, Slowroll, or Leap. I believe the Kernel Of The Day repository is only available for Tumbleweed. By 'latest' kernel you did mean bleeding edge nightly builds, right?
I want to have VMs that are kind of like Arch but a little bit more stable, yet have very latest versions of everything I need with minimal risk (no need for the bleeding edge at all times; Manjaro does this semi-okay with its two weeks grace period).
OpenSUSE has the whole OpenQA thing (<https://openqa.opensuse.org/tests>), although I think bugs may occasionally slip through the cracks. I tend to bounce back and forth between Arch and OpenSUSE Tumbleweed (currently on Tumbleweed because I wanted SELinux and setting it up on Arch is a bit more involved than I like), and aside from the KDE 4 to Plasma 5 transition I haven't had any major issues with either one (though I suppose if I had, booting from and restoring a snapshot on Tumbleweed would have be easier than on Arch because Arch overwrites the kernel while Tumbleweed keeps up to... I think 5 versions).
I don't need 100% of all software. Just a tiny fraction and they're modern tools that are heavily iterated on. Is it possible they have bugs? Very much so!
But "stay on an older version to be safe" is not the panacea many try to pretend that it is. Way too many bugs and security vulnerabilities on old versions as well.
If you’re on debian, there’s the backports repository, And stable means stable in terms of feature. They still patches for bugs and security, and quite fast for the latter.
