Since I only fly “live” and use FSLTL (with their live traffic injection) for ATC chatter I always use liveatc.net for those airports where it’s supported. Nothing beats the real thing. I even wrote a flow widget that automatically launches liveatc website to correct airport where I’m parked (haven’t published yet because still working on the bugs).
Even without that if I leave the default ATC “on” (but not for instruction) I can still hear chatter from other traffic with default ATC while still using p2atc.
