Honestly, I don't like the looks of either the Emden (too plain) or the Chinese, although the knob isn't as bad as in the African. I woulda gone for Africans as they are bigger (more meat when they produce young) but the combination of the knob AND the dewlap made me go

! Plus, the ganders can be aggressive, even after socializing.
And anything plain white just doesn't do it for me. I'd love to get the American Buff ones, or Pilgrims, but they are not good guardians.
And if you want LOUD, the combination of ducks screaming their heads off for no reason (see any of
@WannaBeHillBilly 's videos) and roosters crowing at all hours will give the geese a run for their money.
I should just stick with nice, quiet Muscovy.
