I recently moved from a Yamaha 01V96i to an Allen & Heath SQ5 and so far loving the experience.
One feature I do miss is the ability to group output bus faders, I find it handy to be able to control the output level of AUX fed subs, delay/fill sends, or a center channel, off the main LR fader. I understand you can accomplish this by using a DCA but seems a waste of a channel strip when the main LR fader is always there, especially with the SQ5’s smaller fader count.
Would be nice to see this in future update
