In general, most English translations are going to be over 99.5% accurate, with minimal variance between them. Many scholars agree that the New American Standard Bible (NASB) is the most literal or closest translation in English to the original Hebrew or Greek. Other scholars prefer translations based off of the Byzantium texts alone for the New Testament and eschew the Alexandrian texts, and for them the New King James Version (NKJV) is considered most accurate.
