I would also lean ME.
If you are leaning towards graduate study in aero after your undergrad, ME was the much more common background for the aerospace graduates students that I knew while I was in grad school. As an aside note, the aerospace engineering grad students I knew also were not well-supported by the department financially (while those in Chem E, EE, and ME etc. were -- not sure on civil), so if you are thinking about grad school, that will be something to consider. I know that their studies were often prolonged (I know one currently in his 8th year, which was not considered uncommon) because they couldn't concentrate on research 24-7, since they usually needed a way to support themselves if they weren't taking out huge student loans. It COULD just be the particular program (and the high competiveness to get into it in the first place), but it will be something you should definitely ask about when you are applying to programs if you decide to go that route.
Others can inform you better about aerospace engineering careers straight out of undergrad... or where there may be aerospace undergrad programs.
Good luck!
