IMHO, The New Jerusalem Bible, Regular Edition (NJB). Here's why: http://www.jimpettis.com/bibles/njb.htm
Note that accuracy and literalness are not necessarily the same thing. Thus, the NASB (New American Standard Bible), which is considered the most literal word-for-word English translation, is not necessarily the most accurate translation. Nevertheless, it is a well-regarded translation.
For a non-scholar of ancient Hebrew and Greek to determine *objectively* which version is the most accurate is really impossible. The most experienced scholars are (naturally) involved in these translations! It seems likely that any translator would consider his own translation to be the most accurate, and the ambiguities involved in translation pretty much guarantee that *any* scholarly translation is likely to be a relatively accurate translation. In other words, all scholarly translations are on relatively equal footing. To my mind, the best translations are the ones that give you the most information regarding alternate meanings in the footnotes - as does the NJB already mentioned.
