I don't think I can comment about my own PPL, because I flew with so many instructors in so many types that pretty much everything got covered well by somebody.
But to generalise..
- If you want to learn PFLs VERY well, fly with a microlight instructor.
- If you want to learn RT and systems operation, fly with a military instructor
- If you want to learn to fly by feel and without instruments, fly with a gliding instructor
- If you want to learn to fly procedurally, fly with a young GA instructor.
But the thing I'd say is universally least well taught, and is far too much left to be learned by osmosis, is airmanship.
