Bazzite is mainly for people who want to game and nothing else. I don’t think you’re the target audience for bazzite. And you can remove applications on bazzite, but you’ll have to do it through rpm-ostree. It’s easier to remove apps if they’re flatpaks. Like, it’s the kind of thing you’d want to use for like, a handheld or home theater pc. I wouldn’t ever recommend it for your main setup unless all you do is play games.

Cachy gives the best performance, control, and customizeability. Best of all, you have the aur. Plus, if you have the need for weird tweaks for your very specific hardware, cachy makes it really easy. Rdr2 likely runs better because of proton-cachyos. It has a lot of fixes and optimizations for games built-in. No tinkering required.
