Did Rock Vs. Cena surpass Rock Vs. Hogan?
For the most part, I would say yes. Once In A Lifetime had more time (a year's worth of build-up), social media to work with, a bigger buyrate for its WM, and has its own DVD/BR feature.
As for the match itself being better than Icon Vs. Icon, I'll leave that to you guys to debate on.
Suplex City, Bitch!
