UPenn vs. Bryn Mawr

hi! i was recently admitted to both bryn mawr college and upenn during the regular decision round, and i'm contemplating which one i should attend. i'm planning to major in biology while being on the pre-medical track, and i'm finding myself a little lost in deciding. i'm paying basically nothing for upenn, while i have to take a 5k loan in order to attend bryn mawr.

however, i find myself leaning towards byrn mawr because of the campus environment, and honestly i'm scared of what i hear about penn being really competitive and i don't know if i could handle it. i know this may sound silly, but if anyone could give me advice, i'd genuinely appreciate it!
