Boston vs Houston: which US city feels more interesting and friendly?

I got myself two job offers to work in the US and wondered what the rest of the GaGoverse considered or knew about the two places. I have chosen one for my own reasons but wondered which place others considered more favourably. I have also been to both places but only on vacation and it was quite a while ago.
FYI currently in Portugal if that has any bearing.
