The Navarre Bible has an inferior translation (RSV-CE), but far, far superior notes dealing with many spiritual applications and readings of the text, instead of nearly purely critical questions. It also is complete, in both Old and New Testaments. It relies heavily upon the spiritual writings of St Josemaria Escriva from The Furrow, the Forge, and Christ is Passing By, so the spirituality has a decidedly Escrivan slant (this can be viewed as a positive or negative, depending on the man reading). However, a complete Navarre is over $400 (for the ten-volume hardcover issue; slightly cheaper, maybe, for the seven-volume OT and 12-volume paperback NT). It also has the Latin of the Nova Vulgata in a tiny font on each page, which adds probably 400-500pp. to the entire work. The Latin is so small as to be unusable if one reads Latin fluently (although it is fine for reading small portions), and I use the Clementina Vulgata in any case.
The Ignatius Catholic Study Bible only has the New Testament, Genesis, and Exodus, is much cheaper (around $30-50 for all of it), has more orthodox notes when it comes to text-critical issues, and is in a superior translation (RSV-2CE). The notes are written in a large part by Scott Hahn and Edward Sri, and deals with text-critical issues in some cases more thoroughly than the Navarre. It will likely be published in two volumes when completed.
I own and use both. They are complimentary to one another.
