Hmmmmmm, interesting question. I have the Zassenhaus 151 Box, so I guess that means closed hopper. You know, it might be kind of remote, but I think I prefer a closed hopper. In the past, when I used a large percolator for a while, I would start the grinder with the hopper open, and feed additional beans into it, because it couldn't quite hold enough beans in the hopper for the percolator in one shot. Occasionally, as I would grind with the "door" open, a piece would fly out as I was grinding. Other than that, I can't think of any pros/cons.
