I like PF3 atc chatter because it is real chatter with he AI aircraft flying in the sim, instead of listening to chatter recorded from ATC that has nothing to do with the sim you are flying. I also like the 100 plus controller voices instead of just 2. PF3 redid many of the voices in the latest version, and it has made a big improvement. I use Avliasoft EFB in conjunction with PF3 which gives me all approach and departure procedures, frequencies, airports in the sim, and charts. You can even fly an Rnav approach without vertical guidance, and it will show your aircraft on the proper vertical profile.
