Judging the console as a whole I think it has one of the best libraries of all gaming. I love the fact that right now I have every main Street Fighter game from 1 to 5 on this system. Easily some of my favorite indie games have come out on the PS4 (Helldivers, Darkest Dungeon, Galak Z, Rogue Legacy, etc.) , their first party titles have been amazing (some duds aside, i.e. The Order 1886) and I've really enjoyed messing around in PSVR.
I also have a Switch and that's a great system as well but the PS4 is my main entertainment device and I think the PS5 will continue that tread.
