It is a decision that only you can make. You know your situation and what you want out of postgraduate studies better than anyone else.
A good thing is that you can't lose. Both programmes are fantastic; you got full funding everywhere; and, most importantly, you can see yourself in both places!
So don't stress out too much - yes, choosing is hard, but you are in an excellent position to be in! Perhaps, try imagine yourself in 10 years, think of what it is you want to do, and perhaps then the path gets a bit clearer!
The very best with your choice!
