Pick for proven behavior
ASUS ROG Strix Pulsar XG27AQNGV
Choose the ASUS for TFTCentral's detailed testing, the firmware 1.1.4 fixes, and ULMB 2 modes down to 60Hz.

Both monitors are 27-inch 1440p 360Hz IPS displays with NVIDIA G-SYNC Pulsar, which strobes the backlight while VRR stays active. Both need an NVIDIA GPU for Pulsar, and Pulsar switches off below about 90 fps by default.
Evidence
TFTCentral's review of the XG27AQNGV measured Pulsar working from 76Hz to 360Hz, 454 nits with Pulsar on, about 1.0 ms input lag plus 2.5 to 3.5 ms with Pulsar, and documented firmware 1.1.4 fixing low-frame-rate behavior. Tom's Hardware's review of the XB273U F5 found Pulsar active from 90 to 360 fps with no brightness drop and gave it an Editor's Choice.
Extras
The Acer includes 2 x 2W speakers and a USB 3.2 hub with three downstream ports. We could not verify the ASUS's USB and audio details. Tom's Hardware noted slight wobble in the Acer's stand; TFTCentral noted moderate wobble on the ASUS.
Verdict
Both deliver excellent Pulsar motion. Choose the ASUS for the deeper test record, or the Acer if speakers and USB ports matter.
