Chapman or Pepperdine?

I got accepted into both. If I go to chapman, I’d live with my family (who I like) and I only have to pay $500 a year, but at Pepperdine I’d live in a dorm and pay $15,000. Pepperdine looks nicer and is a Christian (like me) university. I have family living in Orange County that I could live with and don’t have a car yet. I want to study Biology and Chemistry to be a pediatrician.

Deciding between these two currently. Which did you choose and how has the experience been thus far?
