Thank you everyone for your replies!
I guess you are all right, and I can see that. School A is clearly the better choice...it's mostly just my gut I guess.
To answer your question, I feel like I'd be happier because everyone around me seemed to be happy, my POI is really friendly and supportive, and the weather/location is amazing. Also, the coursework isn't as harsh, and there seems to be less of a competitive attitude.
I am making this assumption because the POI is new and eager to get tenure, yes.
School A has a lot going for it... I guess sometimes when making tough decisions people end up choosing between their brain and their gut. Although my gut is telling me school B, my brain is saying school A.
Thanks guys for helping me think about this!
If there are any other thoughts at all, please feel free I would appreciate it a ton
