The Martial Arts Twin Paradox

 Seeing as it's Monday morning we wanted to get everyone's heads and brains engaged, so here is a little teaser to  get you thinking: 

 Consider two brothers who are twins. One twin took the same martial art for ten years straight under a single Sensei  who teaches a single style. The other twin changed both senseis and styles one a year and rotated through both  standup and ground arts. Both practiced diligently. Which one would win? 

 Please feel free to post your answers to the above in the comments section below.
