The main thing about cue mixes though with the right hardware is: they’re Zero latency .
If you start using regular sends then you’ll be at the mercy of latency…which is a bad thing when recording 
Control room is your friend especially with Steinberg hardware.
I agree with Patanjali with regards to iCpro making the cue mixes easier to deal with. If you have Euphonix controllers like myself you can just tab through the sends until you get to the cue mix and then flip the faders so you have levels on hardware faders.
