There's nothing wrong with Ducky quality except for problematic boards they released some several years ago.
These are completely new revamped G2PRO boards with thick, dyesubbed PBT keycaps, and available in 7 (of 9 available) switch types. The cases seem a bit different in the photos so Ducky might have produced a newer case mold.
There are two other keycap colors available: Grey and Blue mods, and White and Grey mods, but only with the standard Blue/Red/Brown/Black switches. Dark Greys will be even tougher to actuate than Blacks.
Product-wise, getting high quality PBT keycaps and wide switch choice makes these the best Cherry MX board available.
