Put me down as one who does NOT like PMC and generally I toss their brass as I've had too many bad experiences with it to continue to reload it. Their ammo is generally speaking OK stuff tho. I'm not sure I'd call it "fine" but it is OK and perfectly useable.
I've had no experience with their primers other than in their ammo. I do agree that in such times of non availability as we're experiencing now you pretty much have to go with what you can find. I'd not buy any more of their primers than it took to get me by tho based on my experience with their products.
So far every time I've tossed PMC brass in the tumble with my other brass it ruined all my brass. It developed some kinda black fungus crap on it that nothing would remove or at least nothing I've found yet. What it was I have no clue but it continues to spread and any brass put with it catches it. I tossed all the brass from those lots and the media and cleaned my tumbler. It happened again each time PMC brass got put in and never when it wasn't. Me I don't use PMC if it's avoidable and don't keep their brass regardless. Same exact thing happened to me with .44 mag, .223 and .30-30 that I can remember.
