To be fair, I haven't seen any of either guy for at least 18 months, but the only top class matches London has are 2/3 Falls v Dragon and the street fight with Michael Shane, and I'm not even sure how far they would hold up now, it's been so long since I watched them.
I don't think I've ever seen Sydal have an actively bad match, and his match against Rave at Final Showdown is better than anything I've seen London involved in except the two matches I mentioned. Sydal is a much better sympathetic face, sells better and his execution is second to none.
London can be pretty good, but he hasn't the personality or x factor to hold my attention. I don't think he ever had the potential of a big fanbase in WWE either, he isn;t as good looking as Sydal (women), his moves look less flashy (kids) and was never particularly 'cool', though to be fair on that count few wrestling characters are. I don't see what unique selling point he brings to the table, whereas I can clearly see that with Sydal.
London is also Mexican and thus doesn't posses the Aryan pure blood of Sydal right?
