This thread isn't about which looks the prettiest though, it's about which represents the most impressive leap over its predecessor. Not necessarily the same thing.

For example, 3D World is very pretty, but Mario Galaxy already looked so good that the leap isn't that impressive, in my opinion anyway.

If not talking about graphics leap only, I definitely go with Zelda U. Game looks so good, and world looks so huge, beautiful and alive. Skyward Sword looks nice, but it was very linear and world wasn't big.

Well no it is mostly about graphics.  But its about the leap, not just the beauty of the HD game.  What he meant is 3D World is a very pretty HD game, at times gorgeous.  But Super Mario Galaxy is a game that holds up remarkably well and thus the gap between Galaxy and 3D World is not nearly as big as Mario Kart Wii and Mario Kart 8, for example.
