I love the comment that the best study Bible is the one that is used! A whole shelf of unread Bible is just so much paper.

Over the years I have gradually abandoned commentaries, because in my experience they explain the easy, obvious verses and ignore the difficult ones.

The advantage of Thompson's Chain Reference is that there are not overt doctrinal notes (although the organization of the topics and some of the comments are not 100% neutral). I have the King James Study Bible (Baptist) and the Full Life Study Bible (pentecostal) and they both irritate me more than help me.

So currently my vote is with Thompson. Find a 4th edition if you can, and a copy printed in the U.S. For a while they were having them printed in Korea and the quality wasn't as good.
