Why did Edge become a maineventer in WWE,but Christian didn't?

no edge was in a lots of mainevent matches as a mid carder in 2005, he carrer sky rocketed to the top when he had the real life fued with matt hardy, his character became more seriouse and he became a world champ, christain was low mid carder in wwe, but found success in tna. WQ-ankle lock how about both. WQ2- sorry dont like the new divas era.
