My favorite is probably Haiku because it has in my opinion the best floating window manager in the world and just overall feels really good to use. Once it develops further I would genuinely consider using it as my main OS on my laptop. I’ll probably always keep a Linux distribution on my desktop for games though.
(Also your explanation for using windows is a little weird. Minecraft Java works just as well on linux as on windows and you can use bedrock edition with mcpelauncher and it works pretty well. I’ve literally never used anything not linux based as my main OS and I haven’t had anything I actually wanted to play not work since like 5 years ago)
