Stainless.
No question. There might be some coatings that hold up better than others, but they are still coatings, exposed to ~1200* and potential rapid cooling all the time. I've seen jet-hot fail, others have had good luck with various coatings, but I'm not a fan. Dropping a wrench on them, trying to access plugs, scratching is a reality as far as I'm concerned.
My Hedman Elites are rusting towards the collectors where there shouldn't be as much heat, but rapid cooling is much more likely from puddles etc. We don't use salt.
Yes, the stainless ones are ~$700, but there should be no worries about them ever failing. Those will be what I buy, when there is an option other than coatings, I'll take it.
