Aayla wins handily. Beyghor is strong, one of the few Jedi who managed to survive order 66 by killing all the clones. He was individually stronger than Jennir, but got beaten by the duo Jennir + Hudorra. Tbh those two are most likely just average jedi master level, and I'm positive Aayla could take on those two so she beats Beyghor after a short fight
