<p>For all intents and purposes, they’ll be quite similar in most respects you listed.</p>
<p>Some notable differences would be:
-Penn has a better night life
-Yale has better campus dining, and MUCH, MUCH better dorms
-Yale is damn near impossible to transfer into, whereas Penn is merely “extremely difficult”</p>
<p>Yale dukes it out with Harvard in football, and Penn with Princeton in basketball.</p>
<p>All in all, since they’re both rather difficult to gain admission, you should apply to both and hope to get into one.</p>
