Had a SRAM chain fail on my MTB, KMC ones have been fine. I'd suggest not making buying decisions on the basis of anecdotes, they rarely bear any relationship to reality.
Chains like all manufactured goods are produced to a tolerance, and with the expectation of a certain life before failure. As with everything, some will fail early, some will last many times longer than their expected lifespan. Buy whatever you like the look of and/or is cheapest at the time.
