This is really tough if we are pitting these two fella's head-to-head.
I'm calling it a draw lol.
But I really enjoy watching the thought process you see with how JAC goes about his work and that natural genuine speed he has with after-burners to boot is just a few of the things that makes him a bolt of lightning on the field and ultimate finisher.
With Vunivalu, he has that excitement-factor where every touch he has on the ball you are always interested on "what will he produce with his run?" And he also has a spot-tackle that can rattle the ones of any opponent he connects his shoulder with.
You don't take a taser to a gun fight!
