There are a lot of options between Arch and Bazzite. Arch is bleeding edge with very few guardrails, whereas Bazzite has a read-only filesystem and tries its hardest to stop you from breaking stuff (e.g. like a console).

I never recommend Arch to new users because there are just way too many ways to break it. it’s a great distro (I used it for 5+ years), but it’s not a good option for new users. I usually recommend Mint, Debian, or Fedora, because they’re pretty stable, popular, and you’re unlikely to break stuff by normal tinkering. I personally use openSUSE Tumbleweed, which is safer than Arch (openQA testing of packages + snapper by default) but still bleeding edge, which works for me, but I also don’t recommend that either just because of how much churn there is in the packages.

If you only want to play games and want something like a Steam Deck experience, Bazzite may be the best option. My point isn’t that Bazzite is bad, but that it’s not the only or necessarily best option.
