It actually isn't too bad, but the Creator Pro has a more solid Z axis and platform. Really, that so far is my only concern, but it is a big one because of how flexible the guide rods are. It is silly how easy it is to move the build plate from side to side especially when the platform is in the middle of the travel. I'm not too fond of the metal side plates, but I suppose they will be ok.

Note also that flashforge extruders and thermocouple will not fit the Qidi. The Qidi uses a slightly bigger diameter thermal barrier, and the thermocouple has 5mm threads instead of the 4mm threads on the Flashforge.
