As a live show, I'm a big fan of the Brazil card 134. Silva - Okami, Rua - Griffen, Nogeira - Schaub, Barboza - Pearson. Atmosphere must have been crazy. Heavyweights card also up there. (mir - JDS)
The last UFC event on Fox was really good. Certainly looked better than a lot of PPVs in the recent year. Apart from that, i'd have to give this some thought, and i'm afraid i'm just too lazy right now.
Some random events off the top of my head: Pride 10 w/ Wanderlai/Mezger and Sakuraba/Renzo Gracie Pride Grand Prix All UFCs in Brazil. Strikeforce: Shamrock/Le UFC 88 Evans/Liddell w/Hendo vs Palhares and Franklin vs Hamil UFC 104 Machida/Shogun and Pat Barry vs Antoni Hardonk in what is quite possibly the best example of a high level kickboxing fight under MMA rules. Affliction: Banned w Fedor/Timmay
The old NYE shows that lasted 6 hours. I liked the 1 hour show in the beginning. I liked the good matches as well as the circus matched. I also liked that crazy woman who said "Antoino MinautouroooOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO NougieraAAAAAAAAAAAAAAA" pitty they cost 3 times more than it cost to make.
Actually last my mma events were not as much favourite but my next favourite not mma but UFC event will be UFC 157.
