Viera might have more choices for hairstyles, but I think Hrothgar got the better styles in terms of fitting with their overall character design. Several of the Viera styles pay no attention at all to the ear placement of the one race they're exclusive to - long styles parted in the centre and going straight under/through their ears.

I'm not sure how you could do that as a designer. Are the teams that disconnected that the people working on the hairstyles don't get to see it with the ear placement?
