Poll Suggestion: Better South Park Creator

also great job with the site guys now i cant change my profile pic

Can you explain to a novice, how one could differentiate between the two creators? Maybe list what each has done - separately as a quick glance through their respective IMDb pages doesn't help. Most people would know their names but not who would be the better or more creative of the two. I'm assuming you might know which creator - say wrote X songs while the other wrote Y songs, etc....
