I’m just not overly thrilled with the footnotes, as they sometimes seem to contradict Church teaching. Overall, however, they are both considered good translations and I wouldn’t discourage someone from using either. Just be aware that even though the study aides have an Imprimatur, they are not part of the inspired text, not always official Church teaching and can reflect the biases of the scholars that wrote them.
My personal preference is the *Navarre *commentary series which is almost completed, and the Ignatius Study Bible, which has released, to date: the four Gospels, Acts, Romans, and I/II Corinthians. See my wesite linked below for more info.
