46 years working on my own motors and I've used lots of products over the years. NGK's have been my favoured plug since I fell out with Champion many years ago. These NGK's seem to keep their gap tolerance longer from which you can conclude they don't wear as quickly. I've never had the ceramic insulator separate from the body. And don't even start me on Bosch plugs. If you want a quality plug at a reasonable price, go straight for NGK Iridum plugs.
