I am using a Ducky Shine keyboard for the last 5-6 years and I am very happy with it.
I've had the Corsair before but the key caps got all shiny after a while and I didn't like the way they felt.
The Ducky has double shot key caps that has a different texture to it and they do not collect oils from the fingers. They feel really nice to type on.
I haven't checked the latest offerings from Corsair but I believe the one Blue has also have the same type of key caps my Ducky has. They were in the process of changing over to these key caps when I got rid of my Corsair kb.
