Normally I would choose pala because he is a tank and farming gold as a tank is very straightforward, you res some orbs/ greens and there you go. On the other hand, a mage can farm lower level dungeons and make some monumental pulls. I prefer the pala because I don't have to loot much but what I hate about him is that he lacks the ability to pull from a decent range, I can't describe how much I hate that part about him.
Anyway, what do you think?
