Whatever my distro ships by default

My distro is running vanilla-stable series with 6.0.12. How does a hardened kernel differ from a stable one?

Arch’s core/linux

The last from my debian.

Probably Stable, I just use distro default (currenlty 5.15.*)

I use the lastest stable from Manjaro, Just upgraded from 6.0 to 6.1

6.0.12 vanilla-stable.

6.0.10-200.fc36.x86_64

On what device?

Edit: I froze all my kernels at 4.20 for the lulz
