The key distinction: eccentric and quirky are usually positive or neutral; deviant has negative connotations; aberrant is the most clinical and neutral of the strong deviation words.

The distinction: nonconformity is positive when it produces better outcomes than conformity would; it is negative when it simply rejects norms without improvement.
How do writers describe aberrant characters in fiction?
Aberrant characters in fiction serve as a lens for examining the norms they depart from. Holden Caulfield’s nonconformity reveals the phoniness of the world he refuses to join. Sherlock Holmes’s eccentricity enables the cognitive capabilities that make him exceptional. The technique: show the aberration through specific behavior, and show what the aberration makes possible or impossible for the character. Deviation from norms always costs something and usually gains something.
