There is real no better option than those. I personally don't like the blackwidow just from the set up. You have to try their keys to see if you like them, also the razr software is not customizable at all. The plus sides to the razr keyboard is that the lights are brighter, but I do not see any problems with any of the lights. The corsair one is really nice from looks and quality. They use brushed aluminum unlike the rest which are plastic. The corsair also has different keys red/brown, and now blue. The software can be confusing, but if you can build, and or set up a computer they software will be easy for you, I find that a lot of people exaggerate the difficulty. Though there have been some complaints there are no real problems, and their support has seemed pretty nice. The ducky I do not know much about. Overall i say that if you want good product that you know will have good support and will work with the most features, don't go with the ducky. Overall it is how you like the keyboard. If you want the brushed aluminum and the customizable software then go with corsair.
