If I needed something by November, and assuming the overclocked G-SYNC module has ZERO negative side effects (the word is still out on that), I'd get the G version.
For many of the titles I play, FPS oscillates quite a bit (depends on scene complexity). In my view, this is where adaptive sync shines, as it makes the resulting animations a lot more fluid. Solving the tearing problem (like V-SYNC does) which is the primary issue most people think adaptive sync solves, I consider merely an added bonus. I'm unwilling to give up my nVidia 1080, and I'm unwilling to give up adaptive sync, so I'm reluctantly tied to G-SYNC. Compared to G-SYNC, the additional 24 Hz refresh rate and the (faux HDR) DisplayHDR 400 rating the F version brings to the table seem minor to me.
If AMD's GPUs were at least somewhat performance and price competitive at the high end,
OR I didn't purchase high end GPUs, I'd go for the F version and an AMD graphics card. Unfortunately, AMD recovering in the high end GPU space seems unlikely to happen anytime soon.
That being said, the idealist in me just can't get past the idea of spending >$1000, in Q4 2018, on an overclocked DP1.2 controller. DP1.2 is outdated technology from 2010, an eternity ago for computer hardware. Simultaneously, I'm baffled by the abysmal state of nVidia's DP1.4 G-SYNC HDR module. IMHO, if nVidia can't offer a better DP1.4 G-SYNC implementation, then G-SYNC is dead. IMHO that means nVidia must either release a better DP1.4 controller SOON (lower cost, passively cooled, etc), or enable VESA adaptive sync (a.k.a. FreeSync) on their cards. Neither of those two scenarios motivates me to spend money on what is currently available.
I'd like to spend money, but nVidia's crappy work in this area is preventing me from doing so. I'm currently twiddling my thumbs and waiting for nVidia to put all their "cards" on the table.
Both F and G are good monitors though, and I learned a lot researching them and reading this thread, which is why I'm still here
