Yea, I do knw 27GL850 is the go to choice for best price performance option. But the one thing that makes me hold on is the GSync Compatible vs the actual GSync module on my XB252Q.
On paper both can work, but is there any real diff?
both can work in reality.
bet you have already know how these adaptive sync technology works, it's as simple as if your game's fps is 90fps, the monitor will auto-switch to 90Hz so that there's no screen tearing and the need of v-sync. this is best known as variable refresh rate (VRR).
there WAS a key difference though:
1. usually g-sync compatible adaptive sync module has a range of VRR, for example 48-144Hz (e.g. 27GL850 and a lot other 144Hz panels), 48-165Hz (e.g. Gigabte FI27Q-P and other 165Hz panels). the adaptive sync module will turn off when fps goes lower than 48. however, with Low Framerate Compensation (LFC) technology found in high end monitors today (incl. 27GL850, FI27Q-P, Asus XG279Q and so on) even when fps goes lower than VRR range the frames will be doubled and VRR will sync it. for example, if your game runs at 40fps, LFC will double it to 80fps and VRR will sync it on 80Hz.
2. original g-sync module basically works on 0Hz - max monitor refresh rate e.g. 0 - 144Hz.
tl;dr =
no difference
