I have just got a CQ-18T and I am impressed. I worked in pro audio for years before I retired, so have a lot of experience of larger scale digital, but this little thing is very capable. I’d have killed to have something like this when I got started doing band sound in the mid 90’s!
The only thing missing from my POV is subgroups with full eq for things like groups of lav mics, but I can live without and it would be a nice bonus if they add them in a firmware update. (Some flexible busses that could be either be an aux or a subgroup would be perfect)
