HELP Emory VS UCSD VS UIUC for pre med

Hi all. I’m an international undergraduate student looking to study pre-med in the US. I have been accepted to these three schools, but still have trouble deciding which to choose for pre-med.

I like a vibrant city but still student-friendly for I like to travel and sightsee, but also a laid-back and engaging environment within the student body.

UCSD’s city is nice, but I heard grades are cutthroat and the student body atmosphere is very competitive. Is this true?
As for UIUC I heard the student body is very diverse and engaging, but there is not much to do in the surrounding city (Urbana-Champaign). Can anyone confirm on this too?

Also, is Emory really prestigious throughout the US? Because internationally (in my country at least) no one seems to know about it… Are the three unis’ prestige comparable? How is Emory’s surrounding area?

Looking forward to your replies!
Thank you so much!
