For some reason out west we use ABS almost exclusively It can be code in some places just like cast iron in commercial. I never saw PVC drain, waste and vent in PVC until I went east and then the Internet.

Ditto - never saw ABS as DWV until I came west. It was all PVC. IIRC the biggest difference in installation is one step vs 2 step. PVC you need a cleaner/primer on the fittings before gluing up, ABS needs only the glue.
