Well there's alot of grapplers who've fought in ADCC, who've practiced alot of Judo.
Jacare, Roger, Saulo, most brazilians.... but if your talking mostly pure Judoka, Then Kikuta and Sakurai are probably the most decorated. Megumi Fuji done alot of Judo. She did pretty decent. Celita Schultz done pretty good.
