I don't understand people that have no preferences. The cities you mention are vastly different in every way. If you do sufficient research on the destinations in consideration you'd have the information you need to be able to choose, which place fits your needs best, and whether it's a good idea to go to multiple locations in 3 weeks or not.
You need to do research on them both here and elsewhere. All the information you need to already out there.
