What Kernel are you guys using?

I have seen some people claiming that custom kernels like zen cachyos offer better battery life and performance.

Is it true ?

Usually just default, but I believe my ThinkPad has zen and hardened as options.

zen has slightly worse battery life, but slightly better performance.

hardened is more secure, but some software (notably Flatpak) cannot run without first running sudo sysctl kernel.unprivileged_userns_clone=1.

Also, my old ThinkPad uses GENERIC (OpenBSD).
