I tried switching about a decade ago, when gaming wasn't really possible. I ended up just not using it. Recently, after proton, I tried to dual boot again, to slowly transition. I chose to install them on the same drive on different partitions, and this worked fine until I booted into Windows one time and it updated and nuked the boot partition. I just swore off Windows at that point because Linux was now handling everything I needed. Anything I wanted with Windows I could live without, and it's been fantastic since.

I was on Fedora then, and I'm on Garuda now. Both are good, but a few things with Fedora annoyed me (they were done for a reason but I didn't like it). Garuda has been great. I've had zero complaints.

Yeah, I'd never recommend cold turkey-ing it. That's a recipe for dissatisfaction I think. A gradual transition is easy and there's so much less pressure when things go awry.
