Well, that depends on your purpose. This is a step-by-step guide
http://www.BibleSelector.com
but here are my "top picks"...in each category, listed in order of preference
<<< general accuracy and reliability >>>
* New Jerusalem Bible
* Revised English Bible
* New Revised Standard Version (particularly for "liberal" Christians)
* Holman Christian Standard Bible (particularly for conservative Protestants)
* New International Version (particularly for conservative evangelical Christians)
<<< original language word study >>>
* New American Standard Bible (for 66-book Bibles)
* Revised Standard Version (for more inclusive Bibles)
<<< very easy-to-read >>>
* Contemporary English Version (a Bible for 5th graders and above)
* Good News Translation (for Roman Catholics and for adults who dislike reading the Bible)
* New International Reader's Version (a Bible for 3rd to 4th graders)
If you want more details regarding why I chose these particular versions, please e-mail me here or from the web site. Here are pages that "list" some of the pros and cons of many of these versions, but the first link will explain *how* each of these things are a pro or con:
