NIV is very readable and evangelical, the Study version is a good buy. RSV / ESV are more literal, NRSV seems to be a politically correct ("gender-inclusive") translation in the same vein.
NEB / REB are very "British" translations, using what has been called rather stilted academic language (blowed if I can see it though).
NASB claims to be the most literal modern version available.
J.B. Phillips is maybe the most readable of the lot. New Testament only.
There are many many others. The best AV is Scofield, because he gives dates, e.g. the date of the creation was 4004 BC (Ussher).
What is so striking is not so much the differences as the similarities. I challenge anybody to find a mainstream version that creates significant doctrinal difficulties.
