This is why the Steam Deck felt like such a revelation when it hit the market. Every review for a pc handheld has used it as a comparison and mentioned the experience of the Steam Deck couldn't be beat for a handheld PC. People wanted ways to install the OS on other devices and that's why Bazzite and other similar solutions were being worked on by the community.
Sure there are games you can't play on Steam OS but that goes for almost any gaming device. Even Windows needs help with community based compatibility projects for older games, as well as solving issues with newer games that prevent them from running. Dual booting is always possible, and with this type of experience it seems preferable to spend as much time in Steam OS or a variant like Bazzite rather than Windows.
For the price of an Xbox Ally X you could get both a Steam Deck and a Switch 2 and be able to play a good variety of games including Fortnite and other games that might require anti cheat, and get the Nintendo games too. You could even afford a Steam Deck and digital PS5 for the same price and have access to a wide variety of games and be able to play in 4k.
