Tom's Hardware did the work and Extreme Tech summarized it. They both conclude: There is no comparison -- AMD Freesync wins this one.

FreeSync, G-Sync Go Head to Head in New Monitor Comparison
[Tested] two new monitors from the same company — AOC — head to head. The AOC Agon AG241QG is a new 24-inch G-Sync panel, while the AOC Agon AG241QX is a FreeSync panel.
They differ in two significant ways: The QG [Nvidia] G-Sync panel costs $600, while the [AMD=Freesync] QX is $320, and the [AMD-Freesync] QX is the absolute and clear winner of the comparison.
the QX panel proved to be far better calibrated out of the box. It also offers a brighter white, deeper black, vastly better contrast ratios, and a much better default experience
As far as FreeSync versus G-Sync performance, the two were identical. No visual differences could be detected in testing. The dynamic range on the QX panel is nearly 2x larger than the QG
This is only one test and the supposedly identical monitors may have had internal differences (besides Sync). However, the AMD-FreeSync panel cost far less -- implying that hidden advantages are less likely.
