I am coming to the same conclusion, although I have not yet bought the CQ20T. In reality, I probably use the group feature once or twice a year, so it's not the big deal I originally told myself it was. Apparently you can use DCAs (Digitally Controlled Amplifiers) on the Mixing Station, but I barely know the software and have not found it yet. It may be my bias against learning new software, but I do not really like the look of Mixing Station.
The consensus does seem to be that the CQ is a step-up in sound quality from both the Behringer/Midas offerings and the Soundcraft UI series, although the Midas and Soundcraft UI24r are supposed to have better mic preamps than the Behringers or the UI12/16s. It has some nice features that the others do not, but there are functional improvements that A&H can make that in future. The original Soundcraft UI firmware did not include many features that we now enjoy, and the current firmware was 3 years after launch.
One final thing, how usable is the WiFi?
Snap, none of mine are interested in Soundcraft's MoreMe app for personal monitoring.
Thanks for taking the time to explain and good luck with the rollout.
