You can always try it in a VM first. Works pretty well that way, and you can get a taste of what you can expect. I did that to practice my setup and make sure certain software worked.
If you want some of the CachyOS upgrades but also want something a little unique, PikaOS is Debian but custom built for gaming. It uses a lot of the same package optimizations of CachyOS, uses their kernel, but it also borrows from Nobara. It has the best helper apps and updater, IMO, and unlike Debian, it's rolling release and has up-to-date GPU drivers. It even has the same kernel picker and scheduler chooser that Cachy has.
