My fiancee is using a ROG Ally. Windows is just so weird on a handheld, their implementation isn't bad for what it is, but man does it get hung up on some weird places. Very interested in moving her to Bazzite.
She had a steam deck before, our cat knocked it down and broke it and a quick fix was purchasing a ROG Ally from our local best buy. (I ended up fixing her steam deck but our kids got their grubby mits on it.)
She actually loved her Steam Deck. She rarely had to do much to make her games work and asked when there was any weirdness.
