In reality I chose The Blackhawk, and a fine choice it was.
So between those two I would choose the Nighthawk. Like sfar said, Raven has refinement and presence in spades. Just a superb little amp.
In terms of power, I've measured 102+dB at the sweet spot with Moab, and that is damn loud. We had some power hog monitors in here, only 87dB sensitivity, and while we didn't measure how loud they went everyone thought it was plenty loud to be satisfied with. Very impressive sweet little amp.
