Why have just either one?
Get one that shows both mph and knots.
Well, I prefer the speed be measured in knots because it's the standard measurement of airspeed in aviation. I can't stand seeing airspeed be measured in mph. I don't mind having the airspeed be measured in knots or both knots and mph.
Both of the LSA's I flew had the Dynon EFIS. With that, in some way, you can go in and easily switch back and forth. I don't recall what both the CT and G3 had them confiugred in, but it probably was MPH. Doesn't really bother me, just have a checklist that reflects the measurment of speed for that specific airplane configuration.

Well don't go to Europe and fly some of those airplanes over there! Kilometers Per Hour will throw your head into a spin!
