Warlocks and mages both have infinite power potential. Warlocks have blown up planets. Mages have become so skilled in the art that the most powerful mage in existence, Queen Azshara casts spells with her thoughts and no one can use magic around her unless she permits it. She can wield arcane fel and void at the same time. So the answer is both. Because both are only limited by their own intelligence, will, and determination.
