Just a word of warning, SteamOS is designed for the Deck (and Deck-like experiences). It's immutable, which creates some limitations. It'll also be set up for the controls on the device, not mouse and keyboard. These probably aren't total deal breakers, but it's worth considering. It's designed to be a fairly locked down console-like experience. If you want a desktop experience, you're better of elsewhere. I recommend Garuda, which has a great preset for gaming and tools to get everything running easily right after the install.

Yeah I hate that shit. I have never logged in with an ms account and I don't plan to

I'm not saying you're wrong, but is it actually more fiddly or are you just used to it working the other way? I hear people often complain about Linux not working exactly how their Windows install worked, but it being them just not used to the work flow. People get so used to dealing with Windows garbage that they forget it exists, but they notice everything when switching to something new so it feels worse even if it's technically better.
