I have a PS4 pro, X1, and Switch. Ever since I got the switch it became my system of choice and the PS4 became my secondary system. As for my Xbox I use it to watch DVDs, Blu rays and stream media.
I have a gaming PC, Switch, PSP, and if I'm in the mood for retro, then either Famiclone or AtGames Megadrive. The Switch and PSP get the most play time lately.
