You can still get a cover, and still have the advantages of better drop resistance and lower weight and being slimmer than a glass back with cover.
I suppose the wear resistance is slightly better than your average cover. Mine looks OK IMO, but it doesn’t look new anymore. I usually put my phone on surfaces like tables or whatever convenient when I sit down, and the edges where the back curves are clearly a bit matte, and there are a few scratches from the incidents. But there is no discoloration or cracks or anything that looks broken or is an eyesore.
