[ Friends ] Open Question : Between my two friends, who seems more clever/witty?

I’m trying to debate which of my guy friends is more clever/witty and I’m having a hard time trying to decide. Neither of them has met the other. My first friend Greg has a trait that defines his whole personality.: Sarcasm. He’s basically a wisecrack, but studies philosophy and definitely knows how to utilize great arguments in debates. My second friend Jacob likes to roast people. He’s more ghetto and is great with insults. There’s this one fat chick that he constantly addresses as “Lardi B.” He can be quite harsh with his roasts, sometimes telling women that they look like a “Down syndrome Amy Schumer,” and then telling guys that their dick has a Napoleon complex. Comparing these two, who seems more clever?
