ST had a better gameplay and better puzzles than PH. It was nearly better than PH, the only thing I find a bit odd is the events, Nothing happened until near the end of the game, when Byrne appears and starts to attack.
PH had a better storyline, but was easy to guess and beat. It's far the easiest Zelda game to date in my opinion. The puzzles were obvious, the tactics the same and the gameplay like before, except you use a stylus, that was a nice start.
