Well, maybe. But the fact stands that comparable games on PS3 run choppier and look worse, especially the lighting, than Nintendo 1st party games on Wii U. Take ModNation Racers and MK8 as an example. I've brought this up several times already and never got someone from the Sony fan base to admit at least this. They keep going "frame rate means nothing" and stuff. Of course it means a lot if the console has the power reserves to run a game at full 60 FPS without a hitch - something I haven't seen on PS3 yet, other than very simple games with low details.
I personally appreciate that Nintendo often sticks to 60 FPS. But when it comes to racing games on the PS3, it's Gran Turismo 6 that's the technical showpiece.
The problem with using exclusives for comparisons is obviously that it's impossible to do an apples-to-apples comparison.
Super Mario Kart is the single best Mario Kart ever!
