Its a tough one. Because i'm loving the Jericho vs Mysterio matches more but the storyline in the Punk vs Hardy is brilliant.
I like the fact that WWE has guys who some people boo and some cheer. Thats only natural in life. Thats why Cena always facinates me because he acts like a face but gets a 50/50 split.
WWE have been clever in doing this angle with Punk against Hardy who is probally as popular as they come in WWE, if they'd have done it against others the heelish actions would have probally gone unnoticed.
I'm not in such a rush for Punk to turn full heel. I like what they are doing with this. Although i think not tagging in is hard to defend but then they both did it.
