Alan I suspect they are the same as the version number is v2.0.

Other than looks I suspect no difference, but the gold controller would make the owner feel more Golden owning one of these.

I actually don't mind the MC controller the way I am using it. Its better than I thought it would be. The wife gave the MP the thumbs up when she did her first run on it last night. Said she had plenty of confidence and power to do her run.

I have the working MP modded to run 30 amps for a few days now max and it came home from the shops cold.

Its settings are.

48v

23amps max I get 30 amps max.

13 amps cont. I get about 15 amps cont.

Really about 24 amps max constantly. So I have a 6 amp spike to deal with. Not too bad. I suspect what you got to watch for when the hub is like spiking at 40 amps and youre seeing 22 amps real time on the CA.
