The question on the poll and the question in the OP are countering each other, in my onion. But, in response to the poll--which of the two was "better", I think I'd go with Twilight Princess. I think game's overall quality exceeded that of Skyward Sword's. But, that's not to say that there were not things about Twilight Princess that were not as great as they were in Skyward Sword, because there are. I just personally think due to the depth, the mood, and elements behind Twilight Princess made it the better game. Certain things were a little iffy, including character development and such, but I think it stayed true to the expectations of your typical Legend of Zelda game, while bravely straying slightly, making different impressions upon each individual player.
To answer the OP post's question, I liked Skyward Sword slightly more in regards to the atmosphere that was set. I honestly loathed most of the development and structure of this game, but for some reason, I just really, really enjoyed playing it. There was something about the exploration that I somewhat enjoyed, but... I want to think why I say I liked it better is the simple fact that... I am a procrastinator. In Twilight Princess, there wasn't nearly as much to do to keep me entertained when I'm too busy staying off-task as there was in Skyward Sword. I could just really take my procrastination to a whole new level in Skyward Sword, and that's really dandy.
But, a recapitulation: in my onion, Twilight Princess > Skyward Sword, but I liked Skyward Sword a bit more than Twilight Princess. Onions are onions, my friends. If you try to attack my onions, you might just chop them enough to make you cry. I'd be careful if I were you.
