Like anything else, there are different quality grades of aluminum wheels. For the most part, we see no more damaged ones than steel. Biggest issue we see is folks not checking their lug nuts after a wheel has been off. After a few miles it seats some, and may loosen up. Thus needs to be tightened. Steel wheels have a spring tension on the nut and won't do that.

AL wheels can often be damaged by hitting potholes or running off the roadsides. AL wheels are generally much more expensive than steel . They are often used by automotive manufacturers, because they can be manufactured in many interesting shapes . They are also lighter than steel, which can reduce the unsprung weight on the various vehicles' suspensions.
Depending on where you live, their maintence will vary. If you are any where near to the rustbelt states, any long term usage often results in corrosion situations. These could be seen as patches, created around road chipping, which damages the final finish. Corrosion can also be found inside the AL rims where the tires seat against the wheels.
The exteriors finishes can be readily repaired by buffing and polishing the affected areas, and then respraying the wheels with an automotive clear finish. Access to the inside of the rims will first need to have the tires dismounted, the rims then mechanically finished smooth, a noncorrosive protective coating added to the rims' inside areas, and finally the tires are then remounted.
Because I own both steel and AL wheels on various vehicles, and live in a rustbelt state with poor roads, I can say that over the long term, the steel are much easier to keep fresh looking, with less tire pressure leakage and fewer damages on poor roads. My trailers have steel wheels with hub caps. Because I run tires with a relatively high sidewall (75) series, I have had no wheel failures. I can't say the same for my truck and automotive AL wheels.
