There about the same tbh, Im a wiz my self with cleric subclass, and friends rogue, as we kill at same rate, just rouges depend on crit and wiz dont, rogues are str wiz's. If you want to kill fast and not die all the time rogue and be like 40% of what people pick, or be a wiz and get used to dieing but with cleric subclass they can take 2 or 3 hits if in protecter.
So your answer stop asking what you should do to be the best and do what you like, btw both suck in pvp, 1 hit both ways. Oh and jobing is realy good if you have a warrior to buff and cleric to heal
