Full compatibility with games, I never need to think or worry about wether or not an update will break compatibility with Proton. Something that had happened a couple times with Halo Infinite and others. Not needing to worry about getting on the bad side of a developer like with Destiny 2. Easily use stores that are not just Steam to hopefully discourage a monopoly that is currently largely on PC gaming. If I want to run things like Discord, OBS, or whatever other thing I want running I don't have to jump through hoops. Finally the ability to use Game Pass games natively. Windows has become my primary driver on my Steam Deck. Does what I need it to do, play games. Some games even run better under 10LTSC compared to SteamOS.
