Quadra Magic, and no, it doesn't. I would still prefer Comet to Ultima.

EDIT2: As for wanting a mastered enemy skills materia over the full set of magic materia - well, duh. That goes without saying. But mastering an enemy skill materia will require using the magic materia, and a buttload of time and information in order to pull off.
Every Enemy Skill, yeah, it takes a lot of time. The useful, relevant ones? Not so much. I don't give a crap about Chocobuckle, etc. Big Guard, White Wind, Trine, and Beta are all readily available on the first disc (Beta can be somewhat challenging to get, depending on your level) and are among the most useful Enemy Skills.
