The two schools are very similar and both sound wonderful, but some things to consider:
1.) Would you prefer to go to an isolated, rural school (SBC) or a school in a bustling city (Meredith)? Both have their pros and cons, of course. SBC has an expansive, beautiful campus perfect for hiking, riding horses, kayaking, etc. Since it's so isolated, that means pretty much all the activity will be happening right on campus. Meredith, on the other hand, is right in Raleigh. There are 100,000+ other college kids right around the corner, plus all the regular amenities and nightlife of a city.
2.) While both colleges will offer tight-knit communities, Meredith is more than twice the size of SBC in terms of students.
3.) Have you visited both campuses? That would probably be the ultimate thing to do to decide!
