INSEAD vs IMD

I recently met a friend of mine in a Parisian Cafe. He's getting his MBA at IMD. I have to admit that I felt a little jealous about their program. While the overall prestige and reputation of INSEAD is greater than IMD, there are a few very cool things about IMD

1. Very small class size. Total class < 100, compared to 450+ for INSEAD
2. Average age is 31+, which means you have a more powerful network (powerful is debatable ofcourse)
3. Intense focus on group work - Everything gets done in a group. INSEAD does a lot of group work too, but we keep rotating groups quite a bit.

If I were to do it again, I'd do INSEAD all over for it's own strengths. But depending on your background, choosing IMD can be a good option..
