For me I'm edging towards Hughes. He's had over twice as many fights and has more notable wins to his name. If we were doing a who's a greater fighter, then it would be a lot closer, but since were comparing there career's, Hughes is a clear candidate. He's defended his belt more times than BJ has and has more notable wins. BJ has a shout because he won a belt in two weight classes, but for me, Hughes has had the better career.
