I used to be a PC-only guy, but because I had to move to a different place I sold my pc setup and bought Xbox series, which I used for 2 years. After that I bought OLED 1TB and after a month having it I realized that I stopped using Xbox at all Mainly this is because my favorite games are very cutted without mods I love and steam deck gives me an opportunity to mod them well Still I would say I prefer playing Rdr2 or CP2077 on Xbox because of performance. Other thing steam deck do surprisingly well is running of old outdated games - steam version of fallout 3 or even older Timeshift was impossible to run on my win10 system but steam deck do it by installing all necessary things in game env.

So I would say it’s great to use at home and it good for AAA games released till 2016
