Not sure if I'd call it the best, but Twilight Princess is definitely my favorite. I'm not sure why, but during that moment it feels much more legendary. This was the only Link for which it wasn't planned for him to get the sword, all he wanted to do was remove the curse. The fact that he happened to be worthy to wield it was a complete coincidence. Not to mention that at this point, the sword had been all but forgotten. The temple where it used to rest was withered away, only accessible by the Skull Kid.
