Are you trying to alienate yourself from AUF/RAA pilots ? FWIW- Senior RAA instructors have to pass the PPL theory exam.
I have flown with many RAA instructors over the years and they have been just as good or better than the GA instructors I flew with. One RAA CFI friend of mine who I have flown with on many occasions was an Airline pilot, a Virgin sim instructor and flew GA for many years in Papua and has approx 24000 hours.
Imo you analyse things too much. I went from a Jabiru LSA55 to a Piper Archer. The Piper is easier to fly out of the two. Basic GA aircraft like the Warrior, Archer, C172 are generally EASIER to fly.
