I fully agree. But here is the point: while the launch with some (or even all) provided airplanes may have been a bumpy one, Asobo keeps working on them! Case in point they just recently announced - and acknowledged - an upcoming fix for the A320neo autopilot (which they found in collaboration with the FBW team).
And also understand that the provided airplanes will never reach “study level realism”. But again: what is provided as functionality (auto pilot, the in-plane navigation systems etc.) should work as expected. But it won’t ever be complete - unless you purchase a custom made “study level” airplane.
