I made the leap a few years ago now, and since getting a (slightly) newer AMD GPU I haven’t had a single problem that I didn’t create by messing around with things without knowing what I was doing. I use steam and the Glorious Egroll version of proton and every game I have wanted to play has worked, even ones that are brand new. No tinkering past the initial steam setup. I don’t really play competitive online games with anti cheat so you may encounter problems that I haven’t if you do.
I use the advanced hardware support version of MX Linux, if that really matters. I had bad experiences with Ubuntu, but haven’t tried it with this machine so I don’t know if it was the OS or the hardware.
I’d say give it another shot on its own drive when Microsoft frustrates you again, you can always swap windows back in if you don’t like it.
