I have opinions only about the KJV, the NKJV, the NIV, and The Living Bible.

My opinion about the KJV and the NIV are mostly based on the fact that I have them in parallel, with Nestle's Greek, on one volume. The NIV seems to take more liberties with the original than the KJV does, although both of them commit their share of mistakes. I am persuaded by this that the NIV translators, more frequently than the KJV translators, succumbed to the temptation to interpret, as opposed to simply translating.

Since the KJV is in many passages meticulously faithful to the original, the vast differences between it and The Living Bible lead me to regard the latter as more of a commentary than a translation.
