Although I disagree about the Delta-13 (standard, Select, Elite) rack's noise being "not that big a deal," I do agree about this product's reliability, durability, and point-purpose design that hits the nail on the head.
I've had my Elite for over 5 years now (since the product's inception), and other than a few scratches on the outside and some "glossing" on the inside (from contact with the balls in the rack), the rack performs just as it did brand-new. I have the leather inserts (purchased directly from Executive Billiards when they first came out several years ago), and I can say the Delta-13 rack products are not complete without them. The difference in noise is something you have to hear to believe:

I agree that the Elite's (and the new product Select's) anodized finish is superior to the baked enamel of the standard rack. Baked enamel, even though is extremely hard, is softer than the metal it coats, and can (and does) chip, just like those old metal pots and coffee cups that you use when camping. When that enamel chips, you now have a significant concave depression in the surface that, if it's near a contact point on the inside of the rack for an object ball, doesn't push that object ball firmly into its spot, and may even allow it to "walk."
Anodizing isn't paint. It's an electrolytic process that actually "stains" the metal. Whereas baked enamel adds a layer (a measurable layer) onto the metal, anodizing doesn't -- the metal is the same dimensions it was before anodizing. Thus, you can't chip anodizing without harming the actual surface of the metal.
The Select is an interesting product in that the Executive Billiards folks found a way to minimize the number of parts used to assemble the rack, while still employing "maximal use of billet material" savings techniques, and using an anodized finish. The best of both worlds, IMHO.
