His match with Kurt Angle at WrestleMania XX a month later. He outsmarted Angle by loosening a boot, allowing him to slip free of the Angle Lock and roll up a confused Angle for the win.
Not just one for Eddie himself, per se, but at Judgement Day 2004, the crowd was white-hot for Eddie. Not only was he at perhaps the height of his popularity, but he was in the middle of a feud with the pseudo-racist conservative JBL, who had garnered heat by denigrating Eddie's Mexican heritage. Judgement Day that year was held in Los Angeles, and the sheer outpouring of rabid support dominated the entire card, where "Eddie!" chants were being yelled all night long.
His match with JBL is also the infamous match where Eddie gets split wide open after a chairshot. note Eddie's attempt at a bladejob was particularly deep because he "got too excited." Although he got disqualified for using the title belt as a weapon, he ended the show standing tall after one of the most brutal brawls of the year, and looking all the more like a Determinator for it.
His ECW matches with Dean Malenko are master classes in wrestling technique.
With the possible exception of their ECW One Night Stand match in 2005 (Eddie was still playing his "selfish prick" heel persona and didn't want to break character even for the one night), pretty much much any match with Chris Benoit.
