It depends on what you want to achieve.
If you want to produce the best pilots/eliminate the less able, then something demanding, with lots of adverse yaw will defeat the less able, and make the Instructor work harder with the ones who make it.
If you want to be able to teach almost anyone who walks in off the street to fly, You need something more benign, and forgiving of hamfistedness. (Is that even a word?) These aircraft can, however lead to sloppy instruction.
I agree with both BPF and Johnm. A good Instructor is far more important than an ideal aircraft, although some aircraft are so benign that some things are impossible to demonstrate in a meaningful way, and learning in something broadly representative of the types of aircraft you are likely to fly in the future is probably best.
All of the Condors I learned to fly in had the placard "All aircraft bite fools"
A truer word was never spoken.
This was in 1972/3 !!
TTH. I too flew Condors in Yorkshire in the 70s. Was G-AYFD one of them?

Ps. Chuck, Get to fly a Chipmunk soon. It has the sweetest, best balanced handling of anything I've ever flown. Now, if only it had another 50hp and a CSU.........
