I would say ED.
It's easier to do good solo huntings hunting with high exp when you are mage. And nowadays any vocation at high levels can do realy really good profits. Moreover EDs are always needed in team hunts, and they also got the option of doing dupla huntings:Ek-Ed, duo hunting:Ek-Ed, Rp-Ed and Ms-Ed.
Solo huntings hunting Ek for me are still realy really profitable, but they do not get that good experience after all.
