DC Sports Header (poll)
Polished has a slightly smoother surface, so flows better.
It allows more heat in the engine compartment. If you have a good CAi, it shouldn't matter too much.
I don't think DC actually makes this though (at least back when i was looking).
Ceramic helps prevent exhaust heat from leaking into the engine comartment, but is prone to cracking, due to the different expansion/ contraction rates of ceramic & steel .
Personally i'd go w/ a Stainless steel if i can find it.

the reason I went ceramic is because it does not discolor as much as the polished unit.
If it cracks, (altough i have never heard of this happening to a 7th gen dc header) I'm sure dc will stand behind thier product and replace it for you.

I have a DC Ceramic and I love the thing. I bought if because it helps exhaust heat from leaking...Don't really care about looks, just how it works.
