+1 to recently making the switch and to PopOS. There are still small experience pains coming from 2 decades of almost exclusively using Windows, but gaming has been pretty smooth, especially for recent titles. Valve has done an exceptional job with the SteamDeck. I hate monopoly like companies as much as the next person, but honestly it is hard to fault their platform. I still get games on GoG and Itch.io occasionally, but man is Steam miles ahead of the rest of the options, especially for Linux gaming.
