Yeah, I always replace the receptacles on the 8" elements with ceramic. Otherwise they burn too quickly.
For universal receptacles, I prefer the frigidaire over the WP. The frigidaire universals have flat brass clips that make better contact. The wp are shaped like an oversize female push on connector, and don't give as good contact as the others.
the problem is that the parts houses treat them all as generic, so I gave up fighting about it. I just order what I want, and take what i get.
I also get pissed that the bases of the coil elements fall off so often. They need to redesign these. Perhaps after someone dies, they will.
