Update:
THIS monitor supports Freesync and is similar to the Benq in price and quality.

(I believe older models had an overdrive issue which was fixable with a firmware update, and that newer models have this fixed by default.)
Both are:
- TN
- 1ms response
- 144Hz
- 24"
- similar price ($250 AOC vs $275 Benq, at least checked at pcpartpicker)
The Benq is 3D, but you can't use that feature without an NVidia card and NVidia 3D goggles.
*On the other hand, Freesync gives you a much, much better experience in gaming than normal, synchronous monitors.
Here's some more info about the latest Freesync driver update to fix the Freesync low-end issue:

That's pretty CONFUSING to most people, so perhaps just watch THIS video from NVidia to understand how asynchronous mode works (update: not the video I thought, but anyway more info can be found online):
