DubTrub - not trying to re-open old 'discussions', but strongly disagree with your statement
One reason the 152 is a better ab initio trainer because the main gear is more forgiving.
.
The 152 is NOT forgiving of high vertical speed on first contact with the ground. Any vertical energy is stored in the sprung arm undercarriage and will catapault the unwary back into the air! A PA28 has oleos which will absorb a significant amount of the vertical energy component and tend to make the aircraft stick once its down.
All IMHO, of course (having used C172 / C152 / PA28 during training).
