I chose EL. Having gone to the rival school for undergrad, I wanted to still live on a campus (not going to get this opportunity again). Plus more people to meet. Fee Hall, of course, is a bit of an old building. I think most of the Canadians chose to be at EL, in my class anyway (it's a new experience for some of them).
I've never been inside DMC, but I've been outside of it, and around Midtown Detroit. It's a nice area, adjacent to the hospitals, and if you prefer having only 50 or so classmates, there ya go. I've been to the Macomb site though; everything is pretty new, and parking is right outside the building (and free!) IIRC. Also, it's a pretty busy Metro suburb, and has malls, food, etc all really close by, and like DMC, has ~50 students.
