There have been many bullshit "comparisons" on other sites as well, most notably Gamespot who really took a long and deep plunge with some of their moronic conclusions. "We decided not to use HDMI cables since the 360 version we used did not have a gate for it." ?
I prefer to see the difference right before me rather than read someones rant on it (someone who could've been paid by either company for all I know).
Besides; the difference (where such is indeed present) lies in platform exclusives. I don't get why so many expect one version to grossly outperform the other on multiplats...
