Cannot see a huge difference between the two really, both deliver the same end result with a high degree of accuracy, depending on the actual focuser, they just look different.
As for the addition of the heater controller, meh, I already have a heater controller and the mount hub pro has heater controls as well as being able to communicate with a Robofocus unit and be fully automated still.
Horses for courses, I'm enjoying mine and you are enjoying yours, that is all that matters.
