That's exactly my experience. I think the reason is that 3/32" chainrings have teeth that taper down much more quickly than 1/8" chainrings' theeth. I am furious that the Alu chainring on my light SS commuter already shows signs of notching, after only 1300 Km!!!! **** that ****. My 1/8" chainring (fast road SS (which I also use for commuting)) has now 6000 Km, and absolutely no sign of notching. The anodizing has suffered a bit here and there, but the shape of the teeth is perfect.
