Both compliment each other well, and of course I have to say Morrison is better. If and when he breaks out as a singles guy again, it would be helpful for him to have some super hot female manager to do his promos. He just needs one big break, and he should be good to go.
The Miz could have a decent singles career too. He's better on the mic, and isn't that bad of a wrestler. He could get lots of heat when he cuts promos, which is always good.
