Original compressor lasted quite a few years. So I suck or the parts do.

The old long axial compressor from decades back was tough and if there was a failure it was the front seal or a pulley bearing so it was worth repairing. When GM came out with the 4 cylinder radial compressor, a new phenomenon became well known and we called it the black death. With the R4 compressor replacement was commonplace.
With every compressor replacement, a new accumulator, and a system flush is a must if it had the back death, which refers to a compressor that had its internals grind up sending dark metal colored oil and debris through the system. We had a liquid cleaner at the dealership that was used with a flushing system to clean the system. Back in those days the flushing system used R12 refrigerant as the propellant for flushing.
I have a VERY low opinion of the R4 compressor, and if you are getting the system cleaned out, and the new compressors are failing, I would bet the compressors are the problem.
Low quality parts are everywhere now. Even on the dealers shelves.
