I am very impressed at what GSYNC does. However, GSYNC doesn't provide CRT motion clarity. It's important to understand what it is doing, however. I have quoted a section from my
GSYNC Preview #1 and also
GSYNC Preview #2:

Strobing: Eliminates motion blur, but not stutters or tearing.
Motion blur eliminating strobe backlights (LightBoost or ULMB) always looks best when strobe rate matches frame rate. Such strobe backlights tend to run at high refresh rates only, in order to avoid flicker (to avoid eyestrain-inducing 60Hz style CRT flicker).
We found that G-SYNC looked nicer at the low frame rates experienced in both Battlefield 4 and Crysis 3, while ULMB looked very nice during Counter Strike: GO. We did not yet do extensive tests on input lag, but preliminary checks shows that ULMB adds only approximately 4ms (center/average) input lag compared to VSYNC OFF or good frame-capped G-SYNC. If you do, however, use ULMB, and you prefer not to fully lock the frame rate to refresh rate, then using a close frame rate works well (e.g. fps_max 118) as a latency compromise, if you prefer the motion clarity of ULMB.
It is a personal preference whether to use G-SYNC or ULMB. As a rule of thumb:
G-SYNC: Enhances motion quality of lower & stuttery frame rates.
Strobing: Enhances motion quality of higher & consistent frame rates.
