All the commentaries you mentioned are excellent, but they all have different emphases. The Navarre, for example, is more pastoral: it has some good historical background, but it concentrates mainly on plumbing the spiritual depths of the Scriptures and what the saints and other spiritual writers have reflected on about certain passages.
The Ignatius series, on the other hand, concentrates more on providing background, cross references, word studies and topical articles, questions for study and reflection, etc. More of a true Study Bible. Both approaches, along with personal meditation and the teachings of the Church, are valuable in really understanding the Scriptures which, as the word of God, are so profound that a hundred commentaries could never exhaust the depths of their riches.
