Writtens? Pac. Freestyle? Big. Pac had the better body of work overall. His albums and MANY of his singles are leagues ahead of Big's stuff. It's still mind-blowing to think that both men were in there early 20's when they died. They had a MASSIVE impact on the music world for such youngsters. In a way, and I don't mean to sound horrible, but could you imagine if they were both around now? They'd be doing duets with that screaming banshee Katy Perry! Pac is a monster of an mc though. Seriously, that dude is top 5 easy.
