I actually use all three and i try to balance the views a little bit with the fourth edition Oxford Annotated Bible. I also have a few other study bibles: The Lutheran Study Bible, The Concordia Self Study bible, The Wesley Bible and the Interpreter's Study Bible. However, being of the reformed persuasion, I tend to spend more time on the Reformed study bibles. and of course I only use the interpreter's Bible and Oxford Annotated Bible for background information, since I do not share the humanistic beliefs of many of the editors of those Bibles.
Having some vision problems, I also tend to use the three that do have electronic versions, namely SOTR, ESV and RSB.
I am a "layman" but I do spend a fair amount of time in study both for personal use as well as for teaching classes for adults in our church.
