The Sharpmaker is the most useful I've found, but it doesn't do two things well - remove a lot of metal quickly when you need to re-do th back bevel, put the final edge on that a well-made smooth steel can.
I use a Razor's Edge system for new knives and those that need a new back bevel. Then, it's all Sharpmaker. Once I have a hair-shaving edge, I grab the smooth steel from my Razor's Edge kit, and give the blade about 10 extremely light (2-3 oz tops) strokes on each side. Doing that always brings the edge up to scary sharp. If you don't have a smooth steel, the edge of a car window can usually work as well.
I spent several years in the restaurant business. A rough steel was useful because it help somewhat to keep a decent edge during the day so you didn't have to go to the stones, getting the knife dirty, and then have to clean it. The steel eliminated the washing at a cost of a lesser edge. For those folks that rely solely on a steel, the rough is the way to go. Once an edge is gone, no smooth steel is going to help - you have to remove some metal to get the edge back.
I will never use a rough steel again because they are abrasive. When you are at the stage of maintaining an edge, an abrasize is not what I want. I want something smooth to bring out that last bit of sharpness.
