This depends on the sumo wrestler and wrestler in question. However, it can generally be agreed that sumo wrestlers are stronger. (However, many recreational/amateur sumo wrestlers are not strong)
World Wrestling Entertainment (WWE) currently has 69 wrestlers (non-wrestlers such as announcers not included) signed to their roster. However, many are either jobbers, currently inactive, or injured.
