The absolute best, IMO, is a Teflon/moly bake-on. Not an option for married guys, frequently, though...
Duracaot is good- I've been using it on most refins I've done in the past couple of years. Mil-spec anodizing is considered "the standard" for hard service aluminum parts; the current spec is hard coat anodize, with teflon-moly overcoat on the M-4, as I recall.
Anodizing has less build up. It is more expensive.
Teflon/Dura have tolerable buildup and reasonable cost, and are DIY without too much serious expense or effort.
Haven't played with the ceramics, but I understand that buildup is about the same as the other spray-ons, cost is about the same. Haven't heard of any significant difference (for equally prepped parts) in durability.
