The powder coated ones have a more uniform finish than the anodized ones. For those who asked for anodized, I picked through the sets I have and tried to send those with the least amount of grain/streaking showing through, but all of them show that to some extent. The upside of the anodized is that they are black on both sides (so not left and right like the powder coated ones) and would be easier to re-finish on your own if you were trying to get a perfect match to the surrounding area. Otherwise, especially after I start picking out the better anodized ones, the powder coated one look better to me.
Anodized on left; powder coated on right.
