You bet, Michael. I'll give you my take on your question (I just graduated in May 2011).
1.Several employers have told me that they think Wharton students might be the best at actually solving business problems "correctly." That is, we are particularly well equipped with the analytical tools to develop insights that are grounded in robust, and sometimes sophisticated, data analysis. Some other schools' programs are more conducive to teaching their students how to arrive at a conclusion "quickly" and to articulate their ideas in a convincing way; this can important when snap judgments need to be made or time is very limited - but it can also lead to decisions that are "wrong." Based on my experience at Wharton and my knowledge of various different students from a variety of other MBA programs, I'd tend to agree with these employers (at an average, aggregate level).
2. Gosh - where to start. For me, it was a leadership trek to Antarctica that arose out of special, unique connections that Wharton has. Such an opportunity (which mixed MBAs and executive MBAs, by the way) was truly something special about the Wharton network and the ability of Wharton to allow for learning in all kinds of environments beyond the classroom.
Hope this helps!
