Yes, most pro gamers run 144 non-sync screens with Fast Sync (you need 2-3x your target FPS for that) as that still has the best overall results. Adaptive sync is mostly for the lower ranges, 85-120 particularly. 30-60 I find G-Sync to be superior to FreeSync but undesirable regardless. In any case, it's always better than tearing or V-Sync. Like I said, though, even adaptive sync has tearing when you hit upper frametime variances (120+ at 144 Hz) but you can avoid that with some tweaking. If you can consistently surpass a certain FPS it's best just to run a cap (ULMB on a G-Sync display is good here as well), yeah, you only gain 1 frame latency which you also will with adaptive sync if you hit the cap. Adaptive sync also gives better response to frametime variance in general but again, if your FPS is always/mostly above a set threshold and you RTSS cap it, it's very similar.
