Which is better?

Sooo, I just accidentally scammed this kid out of his Goliath and I want to put it on my team. But, I don't know if he is better than Ennard or not. Can someone help me out? (Also I want to emphasize that I DID NOT MEAN TO SCAM HIM. I gave him 10K souls and he AGREED to give me Goliath. It was HIS CHOICE)
