Fair enough.
The dungeons in OOT are better designed and far more atmospheric. The Forest Temple for example is amazing in this regard. The Water Temple is most people's least favorite dungeon in the game, but it is still incredibly well designed and more challenging than anything in Skyward Sword. The Spirt Temple oozes atmosphere and is fun, while remaining challenging throughout.
TP has the same formula as OOT and Wind Waker's Earth Temple is outstanding. Just a few examples
Skyward Sword has some great dungeons, but nothing so remarkable to me that it tops the 3 Zelda games I mentioned.
OoT Water Temple is genius. People hate it because it's hard, but it's not unfair in any way. Once you understand the mechanics of the dungeon you have that aha moment and it's very satisfying.
