Really, the only way to compare them like you seem to want to do, is to hook them up to a dyno of some kind. Run them in some type of prescribed (and consistent) test with whatever load (varying I assume to test bursts) while simultaneously measuring input voltage and current (between the motor and ESC to rule out specific changes in ESC efficiency due to inductive loading and whatnot) and motor temps. Then, compare mechanical power output with input power consumed and graph that against motor heat.

Without some type of controlled test, there are just too many variables to effectively compare to the granularity level you want.

Once all testing is said and done, I think you'll find what the rest of us suspect: Feigaos are inexpensive entry level motors, Neu are the cream of the crop (and you pay for it) for when only the best will suffice, and the Medusas are somewhere in between (probably more towards the Neu end of the spectrum) and probably the best bang-for-the-buck.
