詳しい is the everyday word for being knowledgeable. 精通している is more formal and implies deeper, often professional-level expertise. Use 詳しい in casual conversation, 精通している in resumes or formal introductions.
There is no single Japanese word that directly translates 'well-versed' in all contexts. Using 詳しい or 精通している with the appropriate particle に is the safest approach. Avoid trying to translate 'versed' literally.
彼は本当に物知りだ。
He is really well-versed.
