Point is: when you watch the video, first impressions will be split in terms of which looks better.
It's only when you do enlarged frame-by-frame comparisons do you notice the differences. In motion, the game looks identical on both platforms for the vast majority of the time. In that context, I'm not sure how the actual identified differences - of which there admittedly are - constitute as "way too big".
I'm going to assume that I'm less affluent when it comes to recognising such differences, then. If that is so, then I represent the general market of gamers, and not the hardcore ones, and I'm saying I'd be happy in playing BF4 on Xbox One.
