Anyone else notice spark plug quality/life going downhill?

SO I hang around with a pretty large group of car guys. all with various brand preferences of carbs, ignition, etc

some SBC, some mopar, some ford, some HEI, some MSD....you get the idea.

All of us recently have had issues with fouling spark plugs. Had a buddy literally have 8 junk plugs after a few months.

Just left a buddies house with a SBC in a truck that had ran great all summer. Started running rough after maybe 800 miles since a plug change. started running bad. sprayed some water on the headers, 3! Dead tubes! HEI big cap distributor. Tested spark out of the cap and fine...so dead plugs

delco's, champions, autolites…. I run NGK, and i'm sticking with them as I haven't killed one of them yet.

just wondering if anyone else is seeing this trend? or if its just my group of boneheads.lol
