PS4 by far.
XB1 and Switch were close, as done a couple of Game Pass months, playing games I was on the fence about. Probably go with Switch as it's easier to track 75 hours in BoTW, 60 in Pokemon Sword, 40 in Animal Crossing and 30 hours in Hades. Whereas I played probably 10 or so games on Xbox, but dropped some and none of them were super long, like Doom Eternal was probably the longest.
Played a little on PC, but lockdown cut me off from it due to it being in a different house and was needed there more, I really want to play Alyx too, but will have to wait.
No new gen systems.
