Just think about it for a second.
Since most X1 games run at a lower resolution than PS4 games means developers will be able to use much more effects in X1 games.
So it's a trade-off really, the only thing that matters is what find the most important. To me resolution isn't a big deal, especially since 720p and 1080p isn't that big of a difference. But X1 games on the other hand will probably look more polished thus better
This resolution crap needs to stop seriously, since both versions will look good in their own way
What do you think?
