You need to expand your keyboard knowledge repertoire. There are many outstanding keyboards that you did not include in your list, like Owlab, Mode, Singakbd, and TGR.
Agree with Razer. I'm a huge fan and loving my Razer deathstalker v2 pro, but IT KEEPS DISCONNECTING!!!! For 200$, that should not be an issue at all. I've exchanged mine already 3 times....
