My favorites overall are '92 with Flair winning the WWE Championship as it was loaded with big names and for the first time up to that point the Rumble meant something more than just bragging rights. Followed by 2002 which was star studded and pretty entertaining throughout.
My least favorites are 95. The roster was just putrid. An utter embarrassment if not for the memorable finish with Michaels and Bulldog. And last year (2012) which was pretty much a total joke.
Worst was 1999. Not because McMahon won it but because there was only ever a few wrestlers in the ring at once and it was just boring!
LOL I know everybody is entitled to his own opinion but how can you call it boring? In that match happened so much like in no Rumble before or after. In fact this 1 hour match was more exciting than the whole year 2012.
Best: Royal Rumble 1999
Worst: 1995 and the midcard Rumble 2012
