Definitely some different variables to overall durability. I agree on most soft plastics not scuffing as easily but for PREMIUM labeled plastic, IMO, shape retention is a big part of durability. I can roll up a soft neutron ION into a burrito and its springs back to life in a few seconds while after a year+ of heavy driving the bead still looks great. Just like a gummy champion aviar or other similar plastics which truly define all aspects of durability from surface wear to shape retention.
