It’s very frustrating to buy a controller for the Steam Deck. There are all sorts of compatibility issues and restrictions. The PlayStation controller seems to be the one that best accommodates the variety of inputs that the Steam Deck has, including the trackpad. However, the button layout is nothing like the Deck, which uses the Xbox controller pattern.
These are my impressions, but I may be wrong. Any suggestions?
I’d say far from most. A lot won’t even let you set it manually in the settings.
