I got a ps4 because I could use remote play and not take up the tv so that I could play next to my wife. It was ok, but I had to setup my computer on the couch with charger, kind of a hassle. When I got a switch it was a game changer because I could just grab it and flop down on the couch next to my wife. I imagine (I don't have one) the steam deck is basically the same.

If that is what you guys do also then it will probably be great for you.
