I don't know that I see a clear winner.
When you are saying would not mind staying in CA, do you mean for work after graduation?
I think Pepperdine may have a better network of alums overseas (mostly because of the undergrad - it is ranked much higher than the BSchool).
On the other hand, Pepperdine is a massive machine when it gets to the BSchool (many alums/grads) but their quality is sometimes questionable and the sheer quantity is making the value of the network not so high.
I think you could do well with either school. Keep in mind that if you are looking to get into Finance and move to the East Coast, many MBA's there think that West Coast Schools (Stanford Excluded) are a joke and country clubs or at least that was my impression talking to a few.
Have you considered approaching both schools about scholarships?
Both may offer some money if you can get your gmat over 700. That may be the deciding factor.
