For me its 1A and 1B
Team EAW vs. Team ACW was the most deep-rooted match in E-feds history. So much history went into that shit. The whole reason for AWF's death, the whole split between ACW and the AWF 2.0'ers/EAW'ers. The entire E-fed world was in disarray for sure. It was so much legitimate story-telling that went into the written storyline, with faces from the past and present and even younger guys being utilized to bring out the story to its max. The nutcase tyrant leader in Killswitch, the ACW poster child in HBB and many more facets to this thing. Team EAW was also a hell of a force. I'll never forget that massive ACW vs EAW brawl on Turbo a week before TI with a fuckton of people involved. It may have been the biggest brawl in EAW history.
The Jaywalker turn was like selling your soul twice. This man Jaywalker came from being a squeaky clean babyface a year ago who loved EAW and bled EAW to being anti-establishment to eventually caring more about money than profit, and selling EAW out. The character development was fucking heavy. Team ACW winning literally resulted in it being ''ACW Dynasty'' with ACW staff and crew and ACW Championships being defended in an EAW ring. It was just fucking nuts.
Demon vs Scott is 1B, arguably the biggest of all time with so much at stake in storyline and was just amazingly done. The result sen shockwaves through the E-fed world, people were thinking about opening companies, shit got fucking rocked. Demon vs Scott's result had people legitimately shook, it felt fucking real and it damn well couldve been. There was also some damn good character development with Scott being fed up and funny enough, being in a role similar to Jay's of the disgruntled extremist. I still think the ''Anti'' Scott Diamond thing was some of Scott's best work, with the motive behind it and its debut/blossoming. However, the build up to the match was not on the level of the EAW vs ACW thing (and it would be foolish to expect a 1 on 1 match to equal a 5 on 5 clash between two companies to match in buildup). So thats where EAW/ACW gets the edge.
Demon vs Scott was like humanity having a nuclear war. ACW vs EAW was like the clash between several worlds. Cataclysmic no fuckin doubt.
Team DEDEDE vs Team Scott deserves an argument and should be in the number 2 spot, due to the IMMENSE, IMMENSE build up and character building done for that entire match build up. The confrontations, swerves, alliances and etc. Little known fact is there was an idea brought up of Team Scott winning the 5 on 5 (which wouldve happened if i wanted) and me starting literally from NEO back to the top while my teammates are spared. This wouldve been written as a mutiny done by several team DEDEDE members (likely, Tyler and DC in order to turn them heel) with Scott getting the edge. However, I believe Scott wanted no screwjobs in the match because it was too predictable to have a screwjob finish.
Another possible out-come was for the Scott vs EAW storyline to continue past TI, but Scott would come in with 30-50 riot squad members and lay siege over Dynasty (or all of EAW, depending on what Robbie would want to do). This was brought up by Scott and considered, but didn't come to fruition.
YOU COULD ARGUE for the Imp vs Jay vs HBB vs DDD fatal 4 way goat circle match at the EAW Finale as well. I mean put Hulk Hogan, The Rock, Stone Cold Steve Austin and Ric Flair all in their primes in the same ring and this is what you get.
My list would be
1a. Team EAW vs Team ACW
1b. Dark Demon vs. Scott Diamond
2. Team DEDEDE vs Team Scott
3. ''GOAT circle'' 4 way match
