I think I asked this in the past but things change as new developments occur. I have been away from fsx for awhile now and am wondering what the best atc software out there is. I fly mainly jetliners like the 737 ngx or pmdg 777. I have voxatch but have been looking at pro atc x. For awhile it seemed like they vanished but I am not sure that is the case anymore.

I have been using Pro Flight Emulator (PFE) together with FDC Live Cockpit (FDC) for a number of years now and I can highly recommend them. PFE replaces the default ATC and includes many voice sets with different English accents, taxi guidance system both verbal and visual and many other improvements. FDC acts as a copilot, performing checklists ext. also has cabin crew announcements, again with different accents. You can buy them individualy or together. They have been tweaked to work together.
