I've had good luck with Shimano XT and Wippermann 908/808 non-stainless chains on my geared bikes. I've had several SRAM chain failures on my geared bikes, but the SRAM PC1 on my singlespeed has been very reliable. The Wippermann Connex link is nice and much easier to open than the SRAM link. On the other hand, the Shimano chains seem to shift better than the Wippermann on my otherwise all-Shimano drivetrain.
The last SRAM chain I had on a geared bike broke mid-climb and resulted in a trashed rear wheel and a small loss of blood, but that is just my experience.
