The Black Diamond has a much more dramatic drop-off in brightness as you move off-angle and it color shifts as well. On the other hand, the BD will do a better job of reflecting ambient light coming from the side of the screen. I have a 100" diagonal 08-85 DNP and it is plenty bright for me. I have a SIM2 C3X-E mounted at around 13.5 feet. It is spec'd at 2500 lumens, but I don't know what it's really putting out. It has been calibrated, which usually results in a lower output.
