Welcome, glad to help. I'm in your same situation. I got my new monitor some weeks ago, the Aorus FI27Q from Amazon at 400euros warehouse (but perfectly assembled and no ips-glow at all) and i have to say i'm still doubtful and guess why... MOTION HANDLING!
I red/saw TONS of reviews of monitors and 1 thing is for sure : THERE'S NO SUCH THING AS A PERFECT MONITOR. Unless you want to spend more than 1000 dollars you NEED to give up on something, whether it's the response times , or colors , or contrast ratio. VG27AQ is a good monitor but i don't think that is a good solution considering its price ( 550 euros in my country and it's an 8 bit color panel , with a basic design structure, not an ergonomic one if u mind it, but beside that it has a not exciting response time and it still provides overshoot in his best overdrive modes). The only thing i was curious about was the elmb-Sync but it's not worth it if you're very sensitive (like me) to strobe crosstalk artifacts that are STILL there at any frequency.
Before going further with my advices i would recommend you to play around with CRU (custom resolution utility) following the "Appendix A: Manual Experimentation" that you can find at the bottom of the page of this link :
https://blurbusters.com/faq/advanced-st ... sstalk-faq. Maybe you can reduce the crossstrobe
(BUT DONT GO OVER THE MAX PIXEL CLOCK of your monitor).
With that being said, what i can tell you is that you need to go on the LG's if you are sensitive about response times. LG27gl850 and 27gl83A are the only panels (at a decent price) that provide TN like response times (4 REAL ms AVG in GtG in the best overdrive mode) and great image quality at the same time, giving up on some contrast ratio and 21 Hz more you have on the VG27AQ.
Speaking about response times if you want a TN instead , there are a lot of models that you can choose .. the Omen X 27 is a good solution (3ms GtG AVG) if bought for less than 500 dollars. (real 1ms GtG is not possible without significant overshoot errors).
If you want the best strobe quality i would go on a benQ TN and save some money or considering the Viewsonic ELite series if u can find a good price.
I understand that the feature that allows u to use the Adaptive Sync and the strobe at the same time is not implemented on other monitors , but who cares if it just doesn't do its job ( or at least doesn't look like u wish ).
