Maybe. I’m pretty sure Tien mopped the floor with him in DB, but that was a long time ago. I don’t think either of them have enough feats in Super to definitively say who would win, but Tien is consistantly more dedicated to training and has an even trickier arsenal of techniques, so I’d put my money that ways.

And being half human is still being human. That’s genetic diversity, which is not cheating.
