For me it is not, I use my Steam Deck has a way to carry the games that I play with a controller on my PC or Console... mobile. I use an Elite Xbox Controller and rely heavily on the back buttons.
TBH I don't think Windows holds it back when once I am in the game (the part that matters) the experience is the same.

Being able to instantaneously[1] pause and resume games on the Steam deck makes for a pretty great experience. The non-gaming parts also matter a lot in a portable gaming device.
