Physics 101: for our sake, momentum is always conserved in a collision. Kinetic energy is not. The more elastic a collision is, the more kinetic energy is conserved, and the greater the acceleration/the more the transformer will recoil.
The funny thing is, harder surfaces are more likely to result in relatively elastic collisions, meaning that the transformers would recoil more if they were made of tougher stuff. This is why car hoods have crumple zones that deform upon impact, so that the impulse will occur over a greater distance/time.
This has nothing to do with durability. An adamantium transformer would still recoil based on its mass.
Tying this into the debate, fucachump's sad attempt to prove that Kong is more durable than Prime fails miserably, and your nonexistent evidence that Kong can tank armor piercing explosive rounds to the face isn't winning you any votes either.
