yeah, for gaming make sure the resolution match your desired quality settings.
144 Hz without enouth fps from GPU is not worth it. Also note the difference in display size! 24" / 32"
To begin with: you picket two very nice monitors!
tl;dr: Would say it's mostly a matter of taste
if you want a bigger screen with more resolution and a VA-panel -> BenQ EX3203R (2018)
or a bit more economic with a TN-panel and lower latencies -> LG 24GM77-B (2014)
Personally would prefer the LG.
Tests (german, but very detailed):
