Tempted by Just Flights new traffic add on but I want to make sure it works with ATC so it’s not a frenzy. There’s some downsides to Pro-ATC like the voices don’t always match up location wise, and no VFR really. Would be nice if it did that much. I’m all ears to other ATC and traffic add ons a that work together. Any tips ? 

if your preference is vfr (mostly) piston aircraft from regional airports (Class C & D) , you should use AIG's general aviation schedules rather than airline type schedules from UTL etc.using Class A & B airspace.

I believe Vox could be your answer catering to both vfr & ifr, light to heavy and with TTS voices matching local .... it has its own traffic engine which coordinates well with AIG type bgl traffic files.

 

I use ORBX AU and JF Traffic Global, with no problems, I believe more voicepacks are planned for ProatcX, one of the developers has had personal matters that needed to be addressed which delayed updates for several months

Works with Ultimate Traffic Live just fine
