The worst crank I had was with Race Face Evolve crank, bent axle on the left side after two MTB rides . My dura ace 7700 and 7800 cranks are fine, I have one ST carbon crank with octalink that is fine too.We do get brought stuff that is broken, so failures are over-represented in my daily life, but isis wasn't very good, and a lot of glued up components reach a creaky end.
The shimano crank failures were glued, but they were also about the lightest and stiffest available.
Just didn't last well, but nothing lasts for ever.
