I'd wait-n-see before making any judgements on the plane. It may fly like a brick and be as tricky as the B25 in low level maneuvers. It could be as fragile as an egg, too.
Obviously we don't know, but comments from those who flew it wouldn't support such. Its wing loading is about the same as a Mossie's, not sure if that is loaded or bombs gone, so those expecting an A-20G agile bomber are likely to be disappointed, but it was supposed to be tough. It doesn't look like it has much, or any, armor from the front for the pilot so I am wondering how vulnerable he will be.
On the same note, don't be surprised if the B26 is not the same. Me thinks when HTC updates a plane the flight models become more accurate and in many cases it is "worse" that the original model. If that is the case with the B26 I anticipate a chorus a crying similar to coyotes in the middle of winter. We'll see once the update arrives.
The damage model is where I suspect the B-26 might take the hit. There is also always the issue of visibility from the guns and gun arcs.
