I think the main difference is the pour technique used between the brewers differs greatly, and should be taken into account when buying as a gift. The Beehouse is a more user friendly brewer in that you can just basically pour in water and then let it drain. The Hario brewers, with their large hole in the bottom, requires some refinement of your pour technique (pour speed, pour patter, etc) to get the most out of the brewer. I would say the Hario is more for the coffee geek.
Also remember the Hario uses special filters, whereas the filters for the Beehouse can be purchase almost anywhere.
