XBX has clearly a superior hardware in pretty much every way. However, that does not make it automatically better because most of the differences boil down to the RESOLUTION. There are two major issues with that...
1) The vast majority of people do not have 4K TVs, and the difference between 1080 super-sampled images are only subtle, regardless how blown out in comparisons.
2) Diminishing returns to image quality means a jump from 720 to 1080p implies a much greater visual impact than from 1080 to 4K even though technically it would imply the other way around.
Additionally, with the given installed user-base, most third party games will be based on playstation platforms and / or will be scalable around a stable performance (30 or 60 fps with dynamic scaling).
