The majority of pro level drivers in my area are running the FS Noble NB4 and many of them have moved away from Futaba and Sanwa just to try something different. Pretty much everyone agrees that all modern systems are comparable with respect to speed/performance, the only differences will be ergonomics and features like touch screen, etc.


It's not clear which 6Ch FS you are running, but their dated tech has significantly lower resolution where if you were to race the NB4 for a year then went back to a GT-5 as an example, then the GT-5 will feel "notchy" with less precision in the corners. You won't necessarily drive any slower, but the higher precision offered by the NB4 will certainly increase your confidence in feeling more "connected" with the car.
