Unfortunately, what a seat looks like doesn't tell the whole story. Smart fabrics, piping and humps are nothing like so important as width, depth of foam, gel pads, etc.
I'd say in almost all cases, it's better to go to a custom seat guy and say exactly what you want. The one exception I know of relates to Ducati's comfort seat for my ST4, and that has been superb out of the box. Then again, the fact that it is wide, dished and gelled tells most of the story. That Euro-replacement VX/GS seat looks smart but narrow, convex and with a hump that will limit movement when you feel like a change of position.
Just sayin'....
