Re: Which match would you rather see?
Honestly, this idea came to me as I was thinking about how I'd book most of 2013 and then Wrestlemania 30. I had Ziggler holding the WHC for a few months and beating some worthy opponents. His last defense would be (in my world) in an elimination chamber match at the final PPV of the year, Armaggedon. The next night on Raw, he would have to drop the title because of a very serious injury he suffered in the chamber match (kayfabe).
So the Royal Rumble is built up as the winner of the Rumble match becoming World Heavyweight Champion. There will be no PPV in between Rumble and Mania, and the World Champion will face the WWE Champion in a unification match to headline the biggest show of the year. I'd have Punk winning the Rumble Match to set up Punk vs. Bryan (Bryan would obviously be the WWE Champion at this time). However, Ziggler returns and is cleared to compete again, and the main event will be a Triple Threat winner takes all match.
Not sure if that would be the best way to go about it but yeah...
