The Kitchellence 3-stage and the Mueller 4-stage sharpeners are well-built devices. The former has a solid construction with a nice finish while the latter has a sizable body with an extra slot for shears and scissors.

Both would benefit from a lower working section, though the Kitchellence does better in terms of balance, thanks to a metal plate near the base that adds weight and stabilizes it.

The Mueller can sharpen faster and to a higher level of sharpness. The Kitchellence, on the other hand, is much gentler to the edge. 

Your choice between the two thus comes down to what your priority is: If you don't mind spending more time to get a smoother edge, get the Kitchellence. If speed is important, go with the Mueller.
