#4 Christian
In 2011 when Christian won his first world title, Randy Orton was the man to step up and challenge for the elusive belt. This feud was filled with energy as the two competitors possess great in-ring skills, and the WWE Universe seemed to have loved the idea of watching these men collide.
Orton and Christian competed for the prized asset on numerous occasions, with The Viper coming out on top most of the time. The rivalry went on and on with Christian turning heal, and thus giving this feud a touch of perfection. The two warriors went toe-to-toe, giving the fans something to reminisce about.
This rivalry was more of a one-sided one with Orton winning most of the time, but the backing this storyline got from the WWE Universe was immense.
