I prefer the KJV over other Translations. I ind it more accurate and less Biased. I use it as my primary Bible.
I also grew up on it though.
However, I’d also say that I’d use the NASV over the NIV, or any Literal Version over a Dynamic Equivalence any day of the week.
I used the Revised Standard for years and years until one day I was asked to read a particular text. After I read it the leader said, “Er...thanks.” and asked someone else to read the same text. It was as though someone was reading a completely different verse. I discovered then how horrible the RSV was.
After that I never had a particular version that I have liked but I certainly don’t use the RSV anymore. And if versions differ wildly, then I check it out in the Greek or Hebrew. Blue Letter Bible or E-Swords are excellent tools.
