It depends on what you want the translation for.
The King James version, in my opinion, is the best English translation for reading aloud. It was made to be read aloud, and the translators were not only great scholars, but masters of the English language as well. There are versions of the King James that have been modernized, more or less, for the modern reader. Also, it is one of the most accurate translations. But again, the language can be sometimes not understood by the modern person. And it is not 100% accurate; no translation can be.
For literal accuracy, I prefer the Young's Literal Translation. That is what I read most of the time, by myself.
I also have a high opinion of The Message translation of the Bible by Eugene Peterson. It is NOT a literal translation, but is something of a paraphrase intended to convey the message of the Bible to the modern reader, and so it is good for everyday reading when not actually studying. It is easy to read and enjoyable unless you get hung up on the fact that it isn't literal.
