Are Aasimars simply better than humans?

I mean, I want to do a playthrough as a human sword and shield fighter, but it seems like an Angelkin sword and shield fighter will be better. I mean I need the Charisma for persuasion checks, and it feels as if the Angelkin is simply a stronger character. I don't know the intricate details of it, so are there any advantages to choosing human over Aasimar for any build?
