Well, I have always tried for Level 8 with most spells. Especially those that do damage (Fire, Blizzard, Thunder, Cure). Basuna and Esuna are fine at Level 5 because they heal everything at the Level.
But really, the only advantages to having magic maxed at Level 16 is the animation is different (and the obvious increase in gamage). I remember the Ultima animation being worth the hours of grinding.
