Definitely Matt Damon, who I think is also a much better actor than Ben Affleck.
You've seen Guy Standeven in something because the man was in everything.

Damon's been is far more classic movies than Affleck. (Not counting movies they were in together) Dude was in Saving Private Ryan, the first three Bourne movies, the first Ocean's movie, The Martian, Interstellar, True Grit, and Ford v. Ferrari. Affleck just has The Town, Argo, and… I guess that's it.
Throughout Heaven and Earth, I alone am the honored one.

Matt is obese.

Damon is clearly a Beard.

Matt Damon, but lately they both suck. About Even. Except Ben has had the better life, the Better Pussy. So he Wins in the end.

Afflack became famous for helping Matt Damon write the screenplay for Good Will Hunting, although it’s unknown how much was written between them. Damon came up with the main idea and wrote the first draft at Harvard, it’s possible Affleck just tagged along with his own minor suggestions
