Best Fighter of All Time

I just created a poll on my blog, check it out at the bottom of the information that shows up on the right hand side of the page.

The question is "Who is the best fighter of all time?"

I made my vote for BJ Penn.  It was a hard choice between him and Anderson Silva, and I admit that my choice rests partly on BJ having a more engaging personality than Anderson.  If the two ever fought, BJ would need to get it to the ground quick.  His boxing is great, but Silva is a striking god.  If BJ could get it down, I don't think Silva could out-technique him (despite Silva's BJJ black belt)

What about you, who would you choose?  Stop by and vote now!
