I'm looking at getting an endurance frame as a relaxed road upgrade from my gravel bike and have been eyeing the YFR066 by Airwolf. https://airwolfcarbonbike.com/product/yfr066-airwolf-carbon-bike-frame-700c-disc-brake-road-carbon-bicycle-frame-roadbike-frame-carbon-road-disc/

Any reviews on this brand or recommendations for another frame, before I pull the trigger on 11.11 deals?
Frame is about $600, but I am willing to spend $750, if that amount will be enough to get me better quality.

Any help here is appreciated!
Note, I plan on purchasing on the di2 groupset from Merlin or aliexpress and already purchased a yuanan wheelset from Leon, who posts here.
