Well, just like with aefs2, AEFS4 is IMO 2nd to no other SIM and Airbus add-on I have ever used in reproducing the feel of flight...
About to ask a fellow 320/21 NEO fellow airline captain to try it....
My only "experience" comes from a 1hr full flight simulator session (CAE) on A320, long ago - year 2002 !!!
and also from about 6 jump seat flights in 320 and 321... and I honestly find the feel of "hand flying" the Airbus incredibly close to what I recall from those RL experiences, and much better from what I get from other simulators and various Airbus addons...
