Are you kidding me? Compared to the PS4, the Xbone has a resolution or frame rate deficit with the odd slightly pared back effects or texture map. The Wii U on the other hand is pretty much a 7th gen console power wise that struggles to keep up with the 8 year old 360 in some multiplats. There's simply no comparison.
There's a lot more to it than simply resolution and frame rate. If MGS5 was coming out on the Wii U it would look like the 360/PS3 version, The Xbone version looks like the PS4 version including the textures and effects but with half the pixel count. Geddit?
