They are all nice, the HAO is obviously louder than the other two (normalising the three parts individually would have been good for comparison) - but it also seems the HAO is more open sounding, with the BB being the most congested and dark.
I prefer the HAO for amp like drive, whereas I like the BB as a different sound - it IS dark but still has some crunch to it, and it's very even order harmonics, whereas the HAO has some more dirt/square wave tone to it.
