We have not yet info enough to decide these reps were released barely a month ago
As far as I can see:
GEN has P.3000 movement, sapphire crystal and is made of Titanium DLC coated
SF version has P.3000 Clone4, Plexi crystal and is made of SS DLC coated
KW-V6Fac version has inaccurate decorated A6497 movement, sapphire crystal and is made of SS DLC coated
ZFac version has P.3000 Clone4, sapphire crystal and is made of titanium DLC coated
Since overall quality of three versions is good enough, seeing above commented it seems clear than ZFac is the best version available
But we have not info to give a final evaluation. Anyway, aside other possible flaws, the DLC colour and finish are different form the gun lead a bit glossy colour and finish of the gen, and the crystal distortion looks really ugky. Most likely NO Super rep
