My perspective on sharpening systems is this. You need to decide if sharpening is going to be a hobby for you or if it's just a necessary requirement for owning your knives.
If you want a system to sharpen your knives because you love the technical process or the "art of sharpening" and that's where you get your enjoyment, get a Wicked Edge, EP, Lansky, etc.
If you simply want to get your knives really sharp quickly and effectively and don't really care about the "art of sharpening" or the process, get the Sharpmaker.
Either is fine and there is no right or wrong way. Just depends if you want to spend the time and effort with a guided system.
