Y has a medical school on campus - much easier to shadow

Academic rep:  about equal.  (both are a tad below H/M/S, but close)

Pre-med: both are good choices, but Y has a  medical school on campus

STEM rep: P is a tiny bit better, especially in engineering & CS. But Y has very decent and well regarded science programs. 

人文： 兩家都很強。藝術方麵Y更出色

Social life on campus: Y is a little more laid-back and inclusive. More welcoming.  

Business & Law paths: about equal. 但Y更“左”一些

Overall, Y tends to have more happy students.

But they are really quite close overall and they are very solid at the #4 or #5 of US colleges in terms of national and worldwide recognition.
