I'm using razer mamba and razer ornata v2. I used to play with razer deathadder but its broken after 3-year-use and razer blackwidow.
I switched to razer ornata v2 bcz I didn't like key travel on blackwidow keyboard. it was too clicky and long key travel made get tired easily especially you play game like Gunz where you need to press lots of keys very frequently.
