Which Essay Should I Use For My Harvard Supplement?

I currently have three possible essays I could use, but I don't know which one is better? Could someone pick which they think is the best? There is no specific topic or prompt for the needed essay. Thanks in advance!

Check my profile to look up the essays:

well, i like your grandfather essay, but i think they want to know more about YOU instead...
and both of the others are really good, but i think the "New Experience" flows a little smoother.
I really like the way you connected it to the college itself in "I am a Physics Anomaly." So it might be better if you add something similar to those statements: "I want to pursue my own interest, Biology, in a place where I know new ideas are created, where people are constantly breaking down old notions of science, and where even the anomalies are accepted. A place like MIT" into the "New Experience" essay... of course, you should change "MIT" to "Harvard" here...

wow, Can you tell me which universities you are applying for?

your essays are just amazing. You're a wonderful writer. I sure you can make it with any one of them.personally, I like the "new experience most". I think you should use it for your common application, then use the one "who am I?" for Harvard supplement.

Btw, have you decided which one to use for your common application? Then we can better chose from the other two left. :)
