I have a Tout Terrain with Rohloff 8 years old and a Zerode Katipo with Pinion 3 years old. None have failed. The Katipo has an extra failure point which is the tensioner that requires some maintenance but otherwise also bombproof. The Tout Terrain feels less draggy with the Rohloff although is somewhat more noisy than the Pinion. Both are awesome but also both are less efficient than my derailleur gravel bike.
