The ability to run diesel is nice.. I am sure the JM would drink ok it but they don't recommend it so whatever that is worth.. I like to be able to dump my fuel in the tractor if gets too old...
The one difference I noticed the first time I started the Jetsmunt 200 was the difference between a brushless pump and a standard pump and its ability to pull fuel and prime itself instantaneously. If all brushless pumps are similar there is no need for a self priming function on a turbine with a brushless pump.
Standard pumps need to be primed, sometimes voltage turned up, etc to get them to pull fuel until they are wet. The brushless pump on my XBL 200 doesn't. As soon as the program calls for fuel it immediately starts pumping fuel. So there is a bit of a difference between a standard pump and brushless pump, at least on startup.
