I hate it when WWE.com do these polls for example best PPV, Match, Wrestler etc. They seem to reflect whoever is in favour with the company now and appear to be written by people who have no clue about wrestling. The fact that Summerslam 2002 with the classic Shawn Michaels vs. Triple H unsanctioned match and Rock/Lesnar, Angle/Mysterio, Edge/Guerrero, Benoit/RVD in support is just an honourable mention when many consider it to be one of the finest PPV's WWE have ever produced is proof of that.
Other PPV's I would have considered would have been:
Wrestle War 1992 - Just for the War Games match pitting Sting's Squadron vs. The Dangerous Alliance but also featured a cracking tag team match with The Steiners vs.Tatsumi Fujinami & Takayuki Iizuka
Summerslam 1998 - The first and only Summerslam to draw 700,000 buys. Headlined by Stone Cold vs. The Undertaker this also featured The Rock & Triple's awesome ladder match for the IC title.
Spring Stampede 1999 - Probably the last great WCW PPV had quality bouts pitting Juventud Guerrera vs. Blitzkrieg, Rey Mysterio vs. Billy Kidman, Scott Steiner vs. Booker T & Ric Flair vs. Hulk Hogan vs. Sting vs. Diamond Dallas Page
No Way Out 2000 - A quality PPV from WWE's best ever year featuring Chris Jericho vs. Kurt Angle, Hardy Boyz vs. Edge & Christian, The Radicalz vs. Too Cool, X-Pac vs. Kane and the classic Hell In A Cell World Title vs. Career match between Triple H & Cactus Jack.
Fully Loaded 2000 - Billed as having a Triple Main Event this show was focused on guys new to WWF in the featured matches. Jericho, Benoit & Angle were pitted against Triple H in thrilling Last Man Standing Match, The Undertaker in a so-so match and The Rock in forgotten little thriller for the WWF title. Underneath still rocked with a nice six person intergender tag bout pitting the Hardy Boyz & Lita vs. T&A with Trish Stratus, Eddie Guerrero vs. Perry Saturn and the steel cage match for the IC title with Val Venis & Rikishi during which Rikishi splashed Venis from the top of the cage.
Royal Rumble 2001 - This PPV features on the strongest undercards ever seen at a Rumble. Edge & Christian vs. Dudley Boyz, Benoit vs. Jericho in a ladder match and Kurt Angle vs. Triple H all shine. Stone Cold wins a entertaining Rumble match which also featured a career performance and babyface turn from Kane.
No Mercy 2001 - Although the invasion angle wasn't a success it did give us this little cracker of a PPV headlined by Stone Cold Steve Austin vs. Rob Van Dam vs. Kurt Angle for the WWF title and the classic WCW Championship match pitting The Rock vs. Chris Jericho. Also featuring strong support from The Hardy Boyz vs. The Hurricane & Lance Storm, Kane vs. Test, Christian vs. Edge in a ladder match for the IC title and The Undertaker vs. Booker T
Wrestlemania 21 - The WHC & WWE titles match are sadly below par for a 'Mania but Rey Mysterio vs. Eddie Guerrero, the first ever Money In The Bank Ladder Match, The Undertaker vs. Randy Orton and the first ever classic meeting between Shawn Michaels & Kurt Angle make this a quality PPV that should be on the list
Vengeance 2005 - The first two matches were poor but from Edge vs. Kane onwards its gold. Shawn Michaels & Kurt Angle have a first class rematch from Wrestlemania 21, John Cena defends the WWE title against Chris Jericho & Christian and was headlined by an incredibly brutal Hell In A Cell match that was the blowoff to the Triple H vs. Batista feud.
No Way Out 2006 - Boosted by the arrival of Kurt Angle in January Smackdown presented this awesome PPV headlined by Angle vs. The Undertaker for the WHC. A near 30 minute slow building classic which I would recommend to anyone and should really have taken place at Wrestlemania. Rey Mysterio vs. Randy Orton was a good match let down by a distasteful storyline, Booker T & Chris Benoit put on a clinic for the US title and Gregory Helms took on the entire Cruiserweight division in a quality opener.
Unforgiven 2006 - Probably the third best single brand PPV WWE ever presented. Edge & John Cena end the feud of the year with a high octane TLC match, DX take on The McMahons & Big Show in Hell In A Cell, Trish Stratus goes out on top against Lita in an emotional match, Randy Orton & Carlito have a fun match with a great finish and the returning Jeff Hardy and Johnny Nitro have an entertaining if a little long match for the IC title.
Backlash 2007 - This PPV only featured 6 matches but 5 of them were highly entertaining. The Hardys vs. Lance Cade & Trevor Murdoch was a fun opener, Melina vs. Mickie James was fun. Chris Benoit continued to elevate MVP in their US title match. The Undertaker and Batista continued their feud and proved their match at Wrestlemania was no fluke with a gripping Last Man Standing match which sadly has a unsatisfying finish and John Cena, Edge, HBK & Randy Orton had a great Fatal 4 Way for the WWE title
Wrestlemania XXIV - My second favourite 'Mania of all time behind X-7. Featuring 6 good to superb matches I don't understand why this isn't on the list. MITB was first class, Randy Orton defended the WWE title against Triple H & John Cena, Big Show had a fun special attraction match with Floyd Mayweather, Shawn Michaels emotionally retired Ric Flair in a classic match and The Undertaker & Edge tore the house down in the main event for the WHC, the last ten minutes being so seesaw and competitive that you could have believed that Edge could have ended the streak.
Having talked about all these great PPV's I'm now off to watch some.
