Experts have compared the translational philosophy to that of a dynamic equivalent (NIV) for the Battles/McNeil vs. a formal correspondence (ESV, KJV) for the Beveridge. I have read through both of them and actually liked the Beveridge better. However, as others have noted, the notes are quite valuable in the Battles/McNeil edition. If money is an issue, it is $13-15 vs. $60-80.
Since I prefer digital format, when Logos was selling the 108 volume "Calvin 500" collection for a song, I added it. It has Beveridge, Allen, AND Norton (plus the French and Latin)!!!
