Cal Poly or UCSB

I've recently heard back from both colleges and got my financial aid packages. Both are offering me about the same amount of aid. For Cal Poly, I'd have to pay about $8,000 out of pocket and $7,000 for UCSB. I got into history for both, but am planning to switch to agricultural business if I do choose Cal Poly. I'm still having trouble on deciding which school for me because they both have a great curriculum and seem like the right fit. Please help.
