the biggest advantages of the ME super is: Av, 1/2000 top shutter speed, and smaller lighter form factor.
the KM is all mechanical with only 1/1000 top shutter speed (same as with the top of the line MX) it is larger and heaver, and only has manual control.
the ME super also has a larger brighter viewfinder 0.95 x [92%] compared to the KM's 0.87 x [93%]
I would argue against blue (despite being a rather well known MX user and enthusiast) that the ME super is an excellent choice over the MX for most peoples uses. and since the only camera from the k series to feature Av is the K2, I would say go for the ME super. the only thing you will be missing compared to a K2 is MLU and the only thing from the MX is DOF preview. you are gaining in every way compared to the KM. the only drawback to the ME super is that (other than than 125/sec) the ME super uses an electronic shutter and requires batteries (though its not a battery hog) the MX also requires batteries if you want to use the LCD exposure meter in the viewfinder.
