Their both equal? Nah, thats a cop out. One will be better than the otherA few more pixels in the most demanding scenarios (assuming dynamic resolution, which I'm sure most games will have next gen - very few will be locked to 4K) isn't exactly something I would call "game-changing" either. Loading in new data in a streaming type scenario (which most games will also be doing) more than twice as fast could definitely be more noticeable. It's not just about load times (as in loading screens).
At the end of the day, both consoles will be huge leaps over what we have now, each having some advantages over the other. Neither is "more next-gen" than the other.
