It all depends on what you're comfortable with. Do you think that you'd enjoy being a part of a large campus or a smaller one? Do you prefer large lecture halls filled with 200+ students or small classrooms of 20-25? I attend the second largest university in my state and the student population is 35,000. Lectures have 150-200 students while discussion sections have 25-30. When I was a freshman, I really loved being a part of a large campus environment, but now that I'm older, I prefer more of a one-on-one relationship with my professors. I love the diversity found on a large campus, but you can still find that in a small college campus as well. If I were you, I'd write down all of the pros and cons of a large university vs. a small college. Take a look at your list and decide at that point which environment would suit you best.
