My experience has confirmed time and again: steel chainrings will outlast aluminum chainrings of the same width several times.
7075-(T6) aluminum chainrings will outlive 6061-(T6) aluminum chainrings 2 to 1, due to the much higher hardness of 7075 vs 6061 (at parity of temper).
Finally, due to the shape of the teeth which in case of 3/32" chainrings are tapering down very quickly to a tiny point, vs. the ones on 1/8" which maintain a much more "full-figured" shape, 1/8" chainrings will last about 3 times longer than 3/32" at parity of material and temper.
The worst chainrings I have ever used were the 3/32" Rocket Rings. Avoid like plague. The best aluminum chainrings I have ever used were 1/8" suginos and 3/32" Salsa chainrings (I wish they had them in 1/8"). The Surly stainless steel chainring I bought a couple of years ago still looks like new - practically unblemished.
