Get stainless. Stronger, holds heat about as well as ceramic, and won't scratch or flake. I mean, the true test to me of the stainless was when it was glowing. I could put my hand down near it and barely feel any heat coming off, but it was pretty damn bright. Also my ceramic coated x-over didn't have hardly any radiant heat either.
(Note, I didn't do that on purpose. Had the car idling to warm up on a cold morning, stuck IAC causing a 2500RPM idle, and about 20 minutes of sitting there doing it before I came out and realized. That's a lot of exhaust heat).
