The international passport control for the AB flights in TXL is a mess. Hate it. No structure/system - purely chaos... but I think this is part of Berlin

DUS is indeed better for connections, although the walk between gates can be longer than at TXL.
For US-Europe trips, DUS connections generally no longer require a security re-screening on arrival at DUS prior to the connecting flight. The came cannot be said for TXL.
