I recommend that you go the interview and see for yourself. I was also accepted to MI and Western, but Western IMO had a better program for me. I'm not going to lie, it's hard, but that makes it good (If you catch my drift).
One thing that surprised me, frankly is that we have a really high level class. There is one guy with a PhD in neuroanatomy. He used to teach at a med school on the east coast. Also, lots of people are sporting their M.S. I swear that compared to most of the class I am mentally challenged.
Stats for our class (from Dean Adams): 3.6 overall 3.5 science 28 MCAT
Me: 3.5 overall 3.75 science 31Q
You will hear people complaining about this or that, but the truth is that every school in the county produces great doctors (in varying ratios to class size 😉) In the end it's really on you to excel where ever you are. If you want to ask more specific questions feel free to PM.
Edit: In talking with students at MI, one thing that makes me very happy is that Western Podcasts their lectures....MI, to my understanding, does not.
