I'm going to dissect your Georgetown pros a bit:
+ US MBA seems to carry much more weight than European MBA
this may have been true 15 years ago, but not today. Especially doesn't apply to top European MBA programs like INSEAD and LBS.
+ Located in Large Metropolitan
Barcelona is arguably a large metropolitan area.
+ Up & Coming program without the attitude
Not sure what this means. Does IESE have an unpleasant attitude?
+ DC & Mid-Atlantic Alum Network
Valid. Georgetown will likely have a stronger US network although you can check the numbers on LinkedIn
+ Overall Georgetown Prestige in US (Will open doors I'd imagine?)
Georgetown University is prestigious. Georgetown business school/MBA is not. Although you may be able to tap into the greater Georgetown network, but business recruiters will know Georgetown's reputation as a 20-30 school.
