Keith Mathison Ligonier Ministries has a list and discussion of his top five commentaries on Jeremiah at the Ligonier Ministries blog. The list is okay, but I would place Mackay and Kidner in the Runners Up category, replacing them with
2. Jack R. Lundbom -- Jeremiah 1-20, Jeremiah 21-36, Jeremiah 37-52 (The Anchor Yale Bible Commentaries, 1999, 2004, 2004).
3. John L. Mackay -- Jeremiah 1-20, Jeremiah 21-52 (Mentor Commentary, 2004).
4. Tremper Longman -- Jeremiah, Lamentations (New International Biblical Commentary, 2008).
5. Derek Kidner -- The Message of Jeremiah (The Bible Speaks Today, 1987).
