Makeup does not necessarily have to be caked on. It can be nicely done and make you look better.
It's a rarity that anyone looks good without makeup, and if I'll be honest because everyone is based on looks nowadays I'd probably choose the girl with makeup on. I don't know your definition of makeup being 'caked' on but it may necessarily not be. Sometimes people mean it's caked on when it's applied at all.
Anyways, I'd choose the girl with makeup. She'd probably look more put together and it would look like she takes more time with her appearance.
Sometimes I just think the things people say on here are so unrealistic. They don't apply to people irl, seriously.
