Personally, whilst I love my PS4, give me Nintendo games any day of the week over the mainstream stuff on the competition. I find PS4 games to be akin to summer blockbusters, impressive popcorn flicks that you soon forget for the next one around the corner.
I don't believe "the fore" of the industry means lots of terraflops and more power. And before you mention voice chat and online infrastructure, then yes I agree with that being something that Nintendo do lag behind on, but when it comes to the games, Nintendo games stick in my mind a lot more and I find overall a lot more fun. The Wii U has some amazing titles.
