Ghirahim was really fun, since every time you fought him, there was a twist to him and the fight was always fun. Scaldera was pretty fun for me, since the fact that you had to chase him down the ramp added some excitement. It was a little overused though since there was really only one phase to the fight. Molderach, well, he was boring. I really liked the first part, but the searching through the sand was sort of dragging-on. Now then, as for the Imprisoned, I really disliked him, like most everyone here, since by the third battle he just got way overused, especially since it was right after the second one, so he is my vote. Koloktos was probably my favorite boss, even if he took forever to beat. He was definitely challenging and involved skill and speed. Tentalus, unlike quite a bit of people here, was another fun boss for me. I enjoyed that the fight took place before you could even see him, and the whole tearing up the ship that Link is on added a sense of seriousness. The Nayru Flame afterword was pretty cool too since it took place on the remains of the nearly obliterated ship. Although he was easy... The fight with Levias/Bilocyte had a nice twist to it, but again was kind of easy, so that's somewhere in between. I haven't fought Ghirahim III or Demise, so I guess my vote doesn't really count, fully at least. By the way, right now I am just before the Skyloft Silent Realm, I already found the gate, but I just need to play the song and then go through it.
