GSP! All the way, hes good at making everyone he faces look like a rookie. I dont think Penn has what it takes to beat GSP. I dont even think Anderson Silva could be GSP.
It's obviouis that both fighters have improved since there last bout. But I honestly think gsp is the total package. Better at everything but maybe bjj. But gsp is too explosive. look what he did to serra. he smothered him, but serra is no bj. but that will happen to penn. gsp is the best fighter in the ww. div. hands down.
