keyparts, triplus, auto metal direct?

keyparts, triplus, auto metal direct. Fenders...are they all the same? I know the fender thing has been bashed a million times. I want to buy new fenders if, at least I use them for patch panels, if they don't fit very well. Are the new keyparts "zinc" gm cert parts better than the amd triplus fenders? AMD prices seem to be a little better, but they don't claim the zinc primer etc. But, they have told me that they are triplus fenders.
