Which combination of ECs are better?

Piano and Misison trips, house building in Africa, and such. OR Scientific Research, publication of own paper, and being a ball person at the US OPEN?

Speaking as a current MIT student, I can’t tell you, and I don’t know myself. I guess if you were applying for a Ph.D. program in physics or neuroscience, the second one would probably be more relevant. Why is knowing which combo is better an important matter?

MODERATOR’S NOTE:
I’m going out on a limb and assume that none of these are an option for the original poster, or anyone else on College Confidential for that matter. It’s one thing to play the hypothetical game in What Are My Chances with your actual stats. It’s another to ask users to play the game when the stats are not real. Closing thread.
