Well I wouldn't have switched if Microsoft didn't suck... so yeah. If I had nothing to complain about, I would have just stayed on Windows.
I've had Linux Mint running on my ThinkPad T430 for a while now and haven't encountered a single issue. Some distros have awful quality control with their updates (ubuntu) which can cause the issues you've encountered. Going with a stable distro is key for a good experience.
Marvel Rivals has a gold rating on ProtonDB (meaning it works usually without tinkering).
If you're concerned about drivers, use Bazzite as your distro. It manages drivers automatically and comes preinstalled with support for pretty much anything on Steam. In addition to being a highly polished distro with strong gamer presentation.
Mint is great! I use it for my laptop. Lightweight and responsive, perfect for utility. But for my desktop Bazzite is king 😎
