I have to agree with Bob. SEU is the majority here, "protection" is enforced where it is required, per NEC.
My home has PVC Sch80 to the meter pan, & nipple thru the back to panel. That was my personal choice to do it in PVC & copper.
Some people may say.."it gives you the industrial look", but it's my choice.
As an AHJ, I see SEU, PVC, and yes...one of the "senior" (old timers) still does 200 amp in RGC end to end.
