What constitutes good EC's vs. "stellar" EC's?

@MWolf
I appreciate your thoughtful response, and would like to point out that this is not, as it seems like you though, a question that is meant to help me better scheme up EC’s that I think colleges will like. In fact, I am already involved in numerous EC’s that I have gotten very involved in and am very interested in and that I joined for completely non-college related reasons. I just often see people asking for chances of admission and listing crazy things like “performed piano at Carnegie Hall” and “paid intern at the New York Times,” and mine are admittedly much more modest than that, so it can be a bit discouraging.
Additionally, it seems that you think I am looking at these colleges for the name value, or the bumper sticker. In fact, the reason I am potentially interested in these schools is the following, in order of importance to me:

  1. Academic rigor/quality of education
  2. Better out-of-state financial aid
  3. Yeah, it does look good on a resume

It seems you jumped to the conclusion that I am doing this for bragging rights. Nope. Almost everybody I know could give a damn if I told them I went to some prestigious school, and I also don’t place much value in where someone attends school. I just happen to be interested in some specific ones that are competitive.

Still, overall your response was helpful, so thank you.
