They are both good options. The general way I break it down is:

Is this your first Linux PC? Bazzite

Is this a home theater PC or other console like device? Bazzite

Do you have a lot of specialized hardware that needs custom drivers / kernel modules? CachyOS

Do you want to be able to more easily customize parts of the os? CachyOS

Obviously not every case is covered here but hopefully that gives you a bit more of an idea of what each distro is better at. Performance wise they are nearly identical, tbh the biggest difference is that Bazzite is an atomic distro and CachyOS isn't.

Literally my exact question.

I would probably go for CachyOS due to its kernel optimizations. I'm already going with Bazzite for my desktop PC. I'd like to try to figure out CachyOS for the laptop.

I installed cachyOS on my gaming laptop mid last year, and I've been really happy with it. Very few issues I couldn't easily troubleshoot myself.

Not that it's a relevant comparison, but I installed bazzite on my handheld, and had enough problems with it that I installed cachy instead.

I've seen plenty of people happy with either, so I guess it's mostly personal preference re: arch vs fedora, immutable distros, etc etc

@PancakesCantKillMe @firepenny CachyOS runs perfect on my Razer Blade 14.

Do you want red hat like or arch like? Do you want limited OS control or fine grain?
