Obviously no one can make this decision for you, but here is my take.
Since the schools are of roughly the same tier, the deciding factor in "pedigree" will not be the school you graduate from, but the advisor you work with. So: do you know for certain that you can work with the one highly reputed professor you're interested in at school A? If there's a chance that that professor isn't taking new students, or may take some other student instead of you, then I'd say go for the school you'll be more comfortable at.
Personally, I'd rather work with a young, active and amiable advisor than an old crotchety one. And I think the five years of your PhD (most of which will be pretty high-stress) will be a lot more enjoyable in a town/department that you feel at home in.
Just my thoughts.
Best of luck to you.
