I know this is early as today is the first day of a new world at Delta. As time goes on, maybe this thread can become a place for DM's to express their general satisfaction or dissatisfaction with their DM status, without necessarily going into specifics. This would be a useful feedback for those of us who are sitting on the fence.
Maybe this or some version of this thread could become a sticky.
Does DM meet your overall expectations?
In which areas do you think DM gave you an advantage?
Which are the areas where having a DM made no difference at all?
Some are obvious...as you get the same food as a DM as anybody else in the cabin. Maybe FA's could ask DMs for their choice of meal, take their coats first, ask them for pre-departure drinks first.
