Most "important" is too subjective and a pain in the ass to think about, so I'll just list my personal favorites. Also, fuck a top 3, I'm going with top 5.
5. Shane Douglas vs. Bam Bam Bigelow: November to Remember 1997, ECW World Heavyweight Championship - Now, I fully realized that this match was lazy booking, and only happened to re-do the greatness that happened between Ric Flair and Vader at Starcade 1993, but nevertheless... I loved every second of this match. The atmosphere, being in Shane Douglas' hometown of Pittsburgh, was absolutely tremendous and really something special to witness (RVD/Cena from One Night Stand 2006 is the only match I've seen surpass this match as far as the atmosphere in the building is concerned). The match itself wasn't that great, as it was pretty much nothing but Bam Bam beating the living hell out of Douglas, and Douglas selling it like he was dying (The Franchise, in my opinion, is one of the greatest at selling in pro wrestling history). But the last 5 minutes of that match, as I watched it live in my home, all by myself with my Triple Threat shirt on... I will never forget it. When Shane hits that Belly-to-Belly on Bam Bam through the table, I exploded along with the few thousand people in the arena that night. It's something I'll never, ever forget.
4. Homicide vs. Bryan Danielson: Final Battle 2006, ROH World Heavyweight Championship - I had become a huge fan of these guys when I first found ROH in 2004, and even though I absolutely love Danielson and enjoyed the hell out of his run as ROH Champion, there was nothing I wanted to see more then to see Homicide defeat the motherfucker and finally win an ROH Title. And man
. not only did he defeat Danielson at Final Battle, but he did so in a match that was beyond fantastic. I mean, watching the match MONTHS after it happened on DVD, I obviously knew the outcome and I even seen highlights of the match beforehand, but I still found myself thinking that maybe I read the results wrong or something because there were numerous times throughout the match where I thought Danielson was about to retain the title. Thats how great the false finishes in this were. Seriously, if youre looking to get into ROH and you want to know some of their classic shows or matches
I suggest you start with Final Battle 2006, because you will end up viewing one of the greatest, most exciting matches that has ever taken place in in not only the company's history, but in the history of professional wrestling.
3. Rob Van Dam vs. Bam Bam Bigelow: ECW Hardcore TV, ECW Television Championship - I was a fan of RVD before this match, but this is when he started to rival Sting and Raven as my favorite wrestler in the entire industry. Unfortunately, I didn't see this match until about a month or so after it happened, but nevertheless... I was still blown away by it. RVD was spectacular in this match, and made everyone who watched it instantly become a fan of his. Not many Title changes in history have completely made someone into one of the most love, respected wrestlers in the entire business by the people who were fortunate enough to see it, but this is one case where it certainly did so.
2. Shawn Michaels vs. Bret Hart - Wrestlemania 12, WWE Championship - A lot of people here shit on this match, but not me. I remember I had to spend the weekend at my dad's during Wrestlemania 12, and while I was away, my mom ordered and recorded Wresltmania 12 as a surprise for me. So, when I watched the tape, I had zero idea of any of the outcomes, which made it like watching it while it happened. I've always been a huge Bret Hart fan, and today I prefer him over HBK, but during that period, Michaels was my favorite wrestler in the WWF, and there was nothing more I wanted to see happen then him win the WWF Championship. And when he did... it was awesome. The last 15 minutes or so of that match is some of the greatest, most exciting wrestling to ever take place, in my opinion. People say the first 45 minutes are boring or whatever, but not to me. I just see it as building up to the greatest climax that has ever taken place in perhaps wrestling history, so I didn't care about the match being "slow". And even being "slow", the match still told a wonderful story and had some incredible moments (Bret back-body-dropping HBK to the floor, HBK Super Kicking the ring announcer, etc.). But like I said... the '3rd act', so to put it, was just spectacular and something I never get tired of watching.
1. Rob Van Dam vs. John Cena: One Night Stand 2006, WWE Championship - For the first time watching pro wrestling in my adult life, I felt like a kid again. This match made my heart beat. This match had me "marking out". RVD is in my top three favorite wrestlers of all time, and I've so badly wanted him to finally capture that World title for the longest time now. That plus absolutely having no idea what was going to happen, made watching this live on pay-per-view that much more of an experience. The fans in the place were just nuts, which added to my nervousness because I knew if Cena won... something bad was going to happened, but thankfully, it didn't because RVD defeated Cena, and the crowd went nuts with joy, as did I. It was a great, great moment for RVD, and for all his fans such as myself.
Note: For the record, Sting vs. Hogan from Starcade 1996 should have ended up #1 here since the build to it was the most incredible build to a title match I've ever witnessed, but since Hogan and WCW management fucked it up.... it ends up as one of my least favorite moments in wrestling history.
