I am probably one of the MFK's biggest supporters, but even at that, I might have to agree with Coen and Peter, depending on your level of comfort with routing blind in a template.
Personally, I have no issue with it and do it all the time. The major advantage that the MFK has over the other colors you alluded to, is the size of the base. Because of the oblong shape and off-set handle, it is far more stable over open holes, like a hinge mortise.
The standard vertical base has provisions for the typical Porter-Cable style bushings, if you choose to go with a commercially available jig that uses them. Alternatively, you could make your own that would work directly with a top-bearing (template) bit. Though you have to take the thickness of the template into consideration in comparison to the cut-length of your bit.
Peter is correct, the form-factor of the MFK essentially obscures the bit, so if you "need" to see it, like free-hand inlay work.....you're looking the wrong way, but for most other tasks suitable for a non-plunge router, it's great.
IMHO, it excels the most with the horizontal base, but that's completely off-topic.
