Just for reference we had the same topic chewed over here:

This comes up every other year with lots of pro and con opinions. I'm born in and very closely connected with Berlin thru family ties and would love to work and live there. Sadly Berlin has no offerings that I would instantly decide to take up.
TXL is nice, THF was even better. SXF or now rather BBI/BER are not really part of Berlin per se and its a new dimension coming to Berlin. Just like with the new HBf everyone will forget about the finer points once its up and running. LH has said *A will offer a number of longhaul directs beyond CO. We shall see.
