I've been using Gsync since it came out, several different monitors. Gsync IMO makes a bit of difference, but overall it's one of the features midway down the list for me. Having a high hz, as in 144hz to 165, or even anything over 100hz compared to 60, makes more of an impact to me than Gsync tech does. Don't get me wrong, I'll always buy a Gsync lcd because it does make improvements on how the games are displayed, and most of the higher end high hz monitors come with Gsync anyway, but not having it isn't something I'd notice over say being stuck at 60hz.
Good IPS 144+hz Gsync LCD is the best way to go IMO - I use both the Rift and Vive as well, but there are some games, and some instances in certain games, where I prefer not using VR still.
