Key Differences
Idiosyncrasy is a term that often describes deeply-rooted, unique characteristics that differentiate an individual or thing.

Quirks are usually more surface-level traits, not significantly impacting our understanding of a person or thing.
Idiosyncrasy can pertain to systems or things beyond humans, while quirk is generally used to describe human traits.
