Eh, horses for courses. But I consider the 6/23/05 Eddie match to be the best TV match the company has ever done and definitely don't think Generico has a match close to it. Both are great babyface workers who know how to play off of a crowd and work even the most basic opponent into a structure that keeps a crowd invested..but I just think everything Generico does Rey does so much better. Selling, bumping, timing, making the comeback the magnus opus of the match, just everything. The Finlay matches in '06-'07, the Cena Raw match from '11 after MITB, the Henry matches in '06, working in the tag team w/ Kidman in '03, the on and off Tajiri matches in '03-'04, the Raw Chamber at NWO '09 where Mysterio basically brought structure, selling and a dynamite babyface performance that took the match to amongst being one of the better Chamber matches, his week to week TV matches against people like Mcintyre, Gallows and heck even the IC Title match vs Morrison on Smackdown which despite being a match I'm not as high on as others is still a great babyface/babyface title match that elevated Morrison and put him over without having to make either one a subtle heel.
I'm still yet to see the Steen Wolf encounter but I'm just struggling to see Generico having a match close to Mysterio's best. I can sort of see the logic about bigger guys having to sell for him, but wrestling as a whole is built on some serious discrepancies and I find Mysterio one of the better guys at accepting his size and working in that regard to compensate for this small stature and not trying to be someone he clearly couldn't be. Also, as much as I adore him a lot of Generico' stuff could be flubbed and look pretty tame, particularly his strikes. He was a good enough bumper, seller and overall worker to compensate for that, but I just disagree he laps Rey by considerable distance as others are stating.
Should point out I'm in no way calling anyone wrong for saying Generico > Mysterio, since they're entitled to their own opinion and can't be wrong in that regard. I do think the notion that Generico is comfortably better than Mysterio career vs career is naive though, especially since Mysterio's consistency and longevity is what people often cite as being amongst his greater accomplishments.
