Pre-purchase info for PRO-ATC/X and Pilot2ATC

Hi,

I would like to have your comparative impression between PRO-ATC/X and Pilot2ATC, I check the respective supplier web site and I cannot figure wich one to choose.

I Have Also X-Plane 10, P3Dv3 and Headset with microphone. I use also GA and Commercial airliner on short, medium and long distance range.

I know thar RealATC exist for Pro-ATC/X. Does it make an inluent variable on the decision ?

Do you Have a cue based on your experimentation ? On the support ?

Thanks

Michel
