Hmmm...
Well I'd have to say that
tWW battle was
cooler than the
OoT final battle(s). Especially the very end. The first time I saw that part where Link jumps into the air and then BOOM! Lands right on Ganon's head! I swear my heart stopped for a few seconds...that was just amazing.
But in terms of difficulty, I thought that
OoT battles against Ganondorf and Ganon were much more difficult than the final fight in
tWW. They weren't that difficult themselves, I managed to beat Ganondorf without having to go into my first row if hearts, and I didn't even lose any against Ganon; but the fight in
tWW was easier then those two, I only lost a few hearts the first time, and didn't need soup or a fairy.
