For me the gunblade cuz of final fantasy 8, the axe.. easy to make look cool and always looks great with a lala carrying around a big axe, and scythe because who doesn't like being the grim reaper.

Worse for me is daggers, because in vast majority of MMOs daggers end up the size of some swords just so they can have a design to them to the point of I don't understand why we even call them daggers anymore
