Always the same thing, comparing end of gen games with first year games which are made to run on older consoles as well. Pointless owning a new console in the first year(s), unless you like sharper visuals, faster updates, better UI, shorter loading times.
Not that there aren't any improvements besides looking prettier. For example Minecraft's map size on ps4/xb1 is 36 times bigger than on ps3/360. ps3 and 360 were limited by 512mb total memory. We haven't yet begun to see what developers can squeeze out of 4 to 8gb. For now it's indeed just prettier graphics as the game engines still need to run on last gen or were carried over from last gen.
