I have no personal experience whatsoever with these, but the Corsair keyboards have a very bad reputation among mechanical keyboard enthusiasts. Allegedly the keycaps are made of low quality ABS plastic, and because some of the keys are non-standard size, you can’t easily find replacement keycaps.

Among mainstream brands, Ducky and CoolerMaster are supposed to be much better (I have no experience with these either).

I have a CoolerMaster Masterkey Pro L with Cherry MX Browns - Its a nice keyboard, well built and not too showy. I got it for the office and I didn't want something that was very 'gamer-ey'. Only criticism is that the Cherry Browns are nowehere near as nice as the Gateron Browns I have in another keyboard (although I suppose you can't put this on CM). Oh, and maybe the ABS keycaps, they aren't great and the PBT Keycap 'upgrade kit' that CM sell isn't really a direct replacement. I'll probably pick up a separate PBT Double-shot set, but that's optional. I have recommended the CM Masterkeys Pro L to a bunch of people. I had a Corsair K70 (trampstamp edition) a few years ago, and the quality was good but the non-standard bottom row got on my nerves because it severely limited keycap replacement options.

Ducky One 2 user here: it is fantastic for the price. The aluminium case is solid, heavy and beautifully shaped and coated. Switches are perfect to me. Stock keycaps are very good though maybe not the best.

I like it so much I'm using it with both my computers with keyboard/mouse sharing software.

Just bought a Ducky One 2 on my trip to Taiwan and it's a joy to use. All the keycaps are PBT double-shot.
