I have installed PopOS and so far it’s been very stable. Most of the games I play are on Steam and support has been pretty awesome (BG3, CP2077, Valheim, Warhammer 40k: Inquisitor). For non-Steam games, WINE with the Wine Glass GUI has been great, allowing me to run older windows games without a problem.
EDIT: Forgot to add I’m running an Ryzen 7 3700X, 16GB ram, RX 5700XT
EDIT EDIT: +1 for Mint as well. Outside of my gaming PC, it’s my daily driver on my laptop.
