I was also accepted to both schools, and I loved CUSOM. It seems like everyone there knows what they're doing, and although it's a new school, it's definitely heading in the right direction. I also liked the area a lot more than I liked Erie.
LECOM had a weird vibe. It seemed like the students weren't very happy or something. I also got the impression that the faculty only cared about board scores. At CUSOM, it seemed as though the faculty cared about me as a person....and not just about future board scores.
Since you've interviewed at both, I'm sure you know what you like and what you dislike about both schools. I would just go with my gut if I were you. Everyone is going to have different options. I know there are people who love/loved LECOM, and I definitely don't mean to bash the school.
Good luck!
