I don't need to. I have both and in my opinion the quality and quantity I have on PS Plus is far bigger than Gamepass.

Besides I was not trying to be rude or something like that, sorry if I did. It's just that I see that people usually prefer the games that are on PS Plus over the ones on Gamepass. Like God Of War is by itself more popular AND usually much more well evaluated than every game on Gamepass (by critics and players).

You combine that with a wide selection on incredible games like the Final Fantasy games, Saints Row, most of the Ubisoft+ catalogue and some indie jewels like Hollow Knight, a lot of PS1/2/3 games (while Gamepass has only few games of these times) and you have what is in my opinion a much better service.

Of course it all depends on your tastes, maybe you're super into cars and wouldn't give up on Forza even if people paid you to do it. But overall, in a general view of the selections, PS+ is better.
