There is no doubt in my mind that Twilight Princess is better. The story, gameplay, graphics, innovation, and music makes me very emotional in that game. In Ocarina of Time, (played it since I was a kid), it didn't really felt like the best game ever for me. Play it and beat it three times, and I pretty much move on. As soon as I started Twilight Princess, I love it so much, I thought I would explode from the epicness it gave me!
Don't get me wrong though. I don't hate OoT and it's time back in the day as being a really good game. It's just the hype around it just kills it. Sometimes, people who say TP isn't really "Zelda" are the people who were expecting more from the game then they imagine. So they usually grind my balls when they say that.
