Well, variable refresh rate is supposed to be the best new addition to displays since... well... ever. All the benefits of v-sync on with the benefits of v-sync off. It's amazing.
G-sync seems better over all as all framerates up to the maximum are supported, although as long as you stay in the "variable refresh rate window" on freesync displays, you get the same experience.
Have you considered using more than one display? I know if depends on your work space, but I personally keep a u3011 for consoles (as well as videos) at my desk over top of my 3 x Dell 3007wfp-hc's.
