I am writing this on a Ducky One 2 SF with MX Blues. The reviewer is esentially spot-on with this article. The One 2 SF is still a very good keyboard but its feature set is beginning to be outdated. Especially so considering the new generation of Ducky One 3 keebs are factory-equipped with noise-dampening case foam, silicone plate foam, lubed stabilizers and hot-swappable switches.
However, I personally would prefer the One 2 SF's minimalist casing design to the slightly bulkier and more playful one of the One 3 generation. Another upside of the PowerColor x Ducky One 2 SF model is its combination of an ISO layout with Kailh box switches (though I'm uncertain if this configuration has been on offer before). Perhaps more importantly, the PowerColor x Ducky One 2 SF retains the gorgeous translucent keycaps of earlier models in the One 2 SF line while the new Ducky line of models so far has no shine-throughs. In view of the One 2 SF's brilliant RGB lighting, this is a huge plus of the older One 2 SF generation in my eyes. These advantages may make the PowerColor x Ducky One 2 SF interesting to more than just collectors who are after the PowerColor keycaps and the red bottom case.
