I really like PMC since they do not have crimped primers and I have had good accuracy results. Do check them for flash hole placement though, the ones I have seen have had several with off-center flash holes.
PSD is the 'military version' of PMC (AFAIK) and they have crimped primers. I have had good results with them too but you have to remove the crimps.
I would definitely reload them instead of scrapping.
PPU is Prvi Partizan and I have had OK experiences with them in 308, I have not reloaded them in 223 however.
