As long as I still have my Switch, PS5. It has plethora of games I want that are not typically on Xbox, and I have had every Playstation since the PS1.
If I had to give up the Switch to make this choice, it should also be on the poll. In this case, I would go with Switch as it also has a plethora of games I like that are not on PS or XB. Throw in the hybrid form factor and the fact that it is already my primary console because of that, and it becomes the obvious choice for me.
