I think I would love Berlin. It is just very different than all the other options presented, so I was curious why it was listed. It is like someone saying they are trying to decide between several types of dark roasted coffee but also having ginger kombucha in the list. Put more succinctly, I did see a common trait between Berlin and the other locations, so I wondered what it was.
TomK32's provided some great insight as a German. For me, the common traits are 1) local language is not explicitly English, 2) has a vibrant social scene, and 3) I know people there already. I'm a techie so cost of living isn't an overriding concern.
