If you are going ESC AND motors then I would hands down just get an E300 hex kit. I had my doubts but when I got one...my god it is sweet! When they say ZERO vibrations they mean it! you can run the motors full throttle and not feel any vibrations. I use the quad kit on my tbs disco with my GoPro hard mounted to the frame, no padding. It also comes with a power distribution board so you can run the single cable though the arm and make it neat and tidy!
