Youtube is a horrible way to judge anything, ever. Especially resolution...
That said, article is revealing. 50% more pixels at a more stable framerate is huge.
It may not be readily apparent on YouTube, but the extra resolution will be very noticeable while playing.
As someone who owns a gaming PC, Xbox One, and PS4, I will be (actually already have) be buying the PS4 version, and the PC version to double dip later.
After playing 100's of ours of BF4 at a more solid framerate and 50% more pixels, turning on the Xbox One version would instantly give you the feeling that "Something wrong, this looks worse" even if you knew nothing of resolutions.
Like holding an iPhone 4 after owning an iPhone 5 for a year, the extra screen space does not seem like a huge deal, until you try to go back.
