Granted, some of it is trash, but not all of it.
When I replaced the rear bumper on my Jeep GC, I was pleasantly surprised to see the manufacturer's markings on the replacement bumper (purchased from a body shop parts supplier) were identical to the OEM part it replaced. And the bumper cost about a third less than the OEM part from the dealer. Form, fit and function were identical to the OEM.
If I had a "garage queen" or a classic car, I would demand only genuine OEM parts, right down to the nuts and bolts. If I had a "beater", I would want the most "cost-effective" parts. The MO, being less than a year old, is closer to the former. In a couple of years, when it is approaching 50,000 miles I will opt for the latter.
With insurance rates climbing through the roof in New Jersey, you pay through the nose for a policy that provides for OEM parts only.
