A lot of people prefer to shave with wedges, and wedges will also shave better than a full-hollow if both have an equally sub-par edge. This is because the weight of the wedge creates more momentum. On the other hand, all else equal the wedge will take more time to hone properly than a full-hollow because more metal will have to be removed. Even though I would rather shave with a really nice wedge than a really nice full-hollow, I would probably rather hone a full-hollow most of the time because it will take less time to get great results if done right.
