I have always preferred the exclusives that came out on the Sony consoles. I was a PS3 only gamer last gen and that had a weaker GPU and lower resolutions on most early games. For me the Uncharted/God of War/Killzone/inFamous series of games always trumped the Halo/Gears of War/Crackdown experiences.
That said, I have ALWAYS appreciated what MS provided with their Halo and Gears of War franchises. As overrated as those games are, they are still solid campaign experiences that can be played with friends locally and consistently (up to Halo 5), as well competitively online. The same cannot be said of most Sony franchises. One has campaign co-op, the sequel doesn't, then the next one does again bla bla bla.
So yes, in the end I would still play on PS4 no matter the resolution as I prefer the franchises, but that doesn't mean I don't wish Sony would offer those same types of experiences (consistently) that Microsoft consoles have offered.
