I'm really surprised so many people care strongly about curriculum, and so few care strongly about a pass-fail grading system. In my opinion, pass-fail makes the difference between whether you will spend your first two years being happy and relaxed with a lot of free time to play squash, or spend them miserable and preoccupied with grubbing for grades amidst classmates in whom an A-through-F grading system brings out the worst gunneristic tendencies. Also, I feel that anyone who would thrive in a PBL setting would also thrive in a lecture setting, and vice versa; if you're smart and work hard, you can thrive anywhere. You're more adaptable than you think. Just my two cents.
