Without commenting specifically on potato, which I haven't followed closely for the past six months at least, I can point to one major difference which is that there are no coins being accumulated by this. Everything is processed quickly and then sent back to the DAO. You can see the past half day of activity since the proposal went live here, as well as the current balance being zero despite 100 HBD/hour being paid out for the proposal
