Go with AluminumMirageguitarworks could not put it any better.
Aluminum is by far the better choice for wheels, mirageguitarwork is right on the money with his descriptionOne other thing that detracts from steel wheels is that they rustWheel builders used to chrome plate them, but all this did was add weightThe wheels would eventually still rust, and this weakens them even more.
Short answer: Aluminum is lighter and stiffer than steelSteel is stronger but flexierHowever, the technology used to make mountainbike wheels has become very advanced that it is possible to make very strong and reliable aluminum wheels that are at the same time lightMavic and Sun Ringle make strong and light wheelsYou may want to check your local bike shop for their recommendations for your style of riding.
