Anodized — Pass
Powder coated — Chips
High-pressure brushes strip powder coating edges within months
Winter road salt
Anodized — Pass
Powder coated — Rusts
Salt penetrates chipped areas, corrodes the underlying aluminum
UV / sun exposure
Anodized — Pass
Powder coated — Fades
Powder coat pigment breaks down under prolonged UV; anodized dye is sealed
Physical impact
Anodized — Pass
Powder coated — Peels
Minor scrapes peel powder coating; anodized surface remains intact

With powder coating, the color sits on top of the metal. When it chips — and it will — moisture gets in and rust follows. With anodized aluminum, the color is the metal. There is nothing to peel, nothing to chip, nothing to replace.
