1/8" is a lot more durable than 3/32". Also, as I said before, derailleurs change chainline, adding wear to the chain.
Large cogs and large chainrings (with high tooth counts) are better for wear because it spreads the tension over more teeth. Unfortunately, the fashion is going in the other direction. How could I possibly even use an 11-tooth cog?
