Help deciding on which university to choose. I've been offered admission to both NCSU & ECU?

Okay I'm a resident of North Carolina and I'm transferring from a community college to a university in January. Well I have been offered admission to both of my top choice schools which are North Carolina State University in Raleigh, NC & East Carolina University in Greenville, NC. Well ultimately my career goal is to become a dentist and what brought my interest to East Carolina is the fact that they have built a new dental school there, but right now that is irrelevant b/c I've got to finish undergrad before going there. Either way I would apply to dental school there and to the existing dental school at UNC-Chapel Hill when that time comes. Well for my undergrad I would like to major in Microbiology because in case I don't get into dental school the first try I could find a good paying job in that field in the mean time. Well NC State university does have that major but East Carolina does not offer that major, so if I do attend ECU I'll have to opt for Biochemistry instead. NC State is closer to home, even though I do plan on staying on campus. ECU would be 3 hours away while NC State would be 2 hours. Also NC State is better known, better rep, more popular, I think ranked higher academically too. But I like ECU too and the new dental is really what cathes my attention and I don't know if going there for undergrad would increase the chances of them accepting me into dental school being that they might have 1st preference for applicants from their own. They also have a very good medical school there so I'm sure there are many pre-med studetns which I would find lots in common with, same goals etc....while NC State has a Veterinary School. So I dunno, help! I'm in a dilemma I want to go to a good school for my undergrad degree and I'm looking at what undergrad major would offer me the most in case I don't get into dental school as back up. Please help! Thanks!
