Frame Rate Target Control is provably the most consistent frame rate limiter available. The evenness of the frame delivery surpasses RTSS, Chill, and in-engine limiters. This makes a huge difference to the smoothness of recordings. While most pundits in the media seem obsessed with tiny differences in input latency, many of us are more concerned with consistent frame times and are more than happy to sacrifice a small amount of input lag to achieve the unmatched smoothness of FRTC.
Here is a link to a video file download that compares recordings made with the different limiters.

As you can see the display times using FRTC are by far the most consistent, it's not even close. RTSS is second best.
