They all based on off the shelf 80/20 profile and besides vendor reputation and track record you need to look at the level of customization each provides, like custom mounting brackets, front mount for DD wheel, mounting plates for shifter, handbrake, etc. By looking at TREQ it seems mostly basic profile held together by standard angle brackets, more like sim-lab GT1-EVO. I'd suggest to look at sim-lab P1X if you need something more robust, esp. if you are planning on using DD wheel that requires solid, flex free platform.
