I'm constantly getting called out to rewire residential garages. At first, I always piped them as it seems to me that wires are very much subject to physical damage in a garage (lots of hazards in garages such as tree saws). Over time, I have realized that I'm very much in the minority, so I started using NM cable instead. Many garages have some portion sheet rocked. At the moment, I've been using RNC on those portions that are sheet rocked. However, article 334 mentions that NM cable can be run such that is "closely follows the surface". This begs the question: "Is NM secured to the surface of sheetrock compliant to the NEC"?
