It’s always tough when you make a decision. One truly never knows - til you’re there. Maybe you have a bad roommate or bad professor or get home sick. Maybe it’s just too small.
You don’t know - but let’s say you panic and pick the other - the same situation applies.
It could very well be that both work out for you - one never knows.
But go with your gut - what you feel right now says Vassar and as a bonus, it’s cheaper.
Life is long. Hopefully it works out and it likely will (I read on a third party site that retention is 96%) but if for some reason it doesn’t, that’s ok too. Life is long and full of the unknown - and that’s what makes it exciting.
You’ve got two great choices here but it’s clear you prefer one - and I’d be there. If it makes you feel better, it’s got much better “cache” in the name too - at least in my opinion.
Good luck.
