The quality of your PPL is almost totally dependent on the quality of your instructor. What airplane you do it in is IMO irrelevant. The only caveat is that the more complex the aircraft the more structured the aircraft system operation training must be.
I instructed a student from zero to PPL in a Nanchang CJ6A. So geared supercharged 9 cylinder radial with cowl shutters and oil cooler shutter, variable pitch prop, powerful split flap, retractable gear with pneumatic brakes. The first 10 hours of flying training was entirely about learning how to operate the aircraft systems. with me doing all the flying. After that the flying training proper started with attitudes and movements. From that point on the student took about the same amount of time to master the air exercises than if he had been flying a Cessna SEP.
