Which spell is better would solely rely on the type of mob being fought and the difference in level between the mob and the party since higher level mobs result in penalties often time in defense, accuracy, evasion, etc. X amount per level. I think I saw somewhere.
For instance if you are constantly fighting mobs more than 3-5 levels above you in a 3-6 perosn party then Enblizzard/enstone/enwater and enaero would probably be the most used ones overall.
