You might think you can avoid cosmetic problems with aluminum but it will corrode and that means shorter life perhaps right there. is it a bad quality if the paint bubbles and gets the white dust under it?.

also glad that my road bike is steel and the mountain bike is aluminum, or maybe that's not really a good thing.
60xx series (6061) aluminum should be fairly corrosion resistant (it is used with salt water applications
70xx series (7075) aluminum has higher tensile strength, but is more prone to corrosion.
