History subfield at UW-Madison or Yale?

[WorkingItOut]

[posted elsewhere before I realized this board was probably a better fit; got some good advice (thanks, rising_star!), but wanted to see if there are a few more perspectives over here]

 

 

My situation is as follows:

 

I accepted my fully-funded MA/PhD offer from UW-Madison before the April 15th deadline. I had visited the department and feel very positive about the city, the people, the program, and the research fit. UW-Madison is very highly regarded in my field.

 

On April 16th, I received notice from Yale that I have been offered a similarly generous package in their PhD program. This is also a great department and seems like an excellent research fit, however I cannot comment on the people or the department culture as I had not visited (the acceptance is something of a surprise). I am a little bit starstruck by the prestigious name of the institution

 

I'd love to hear some input on what I should do. It seems like there might be some flexibility in declining my first offer, although I'm still not sure if that is what I should/want to do. 

It is my intention to pursue an academic career in my Humanities-related field. 

 

Any thoughts?
