What about Vova Galchenko? (One of the other jugglers mentioned in the article - the one Anthony inadvertently got into a "competition" with).
As far as putting on a show and performing with poise, Gatto easily wins. In at least some specific areas like clubs, Vova seems to rival him though. He is really consistent and has demonstrated he can perform pretty well too. Here's a direct link to Vova's video [0]. This is probably one of my favorite juggling videos to watch.
Incidentally, I believe Vova has moved on as well- he got a degree in Computer Science and is doing software development these days. His sister Olga has also gone on into engineering.
