I guess the King James Version because I love old English
Not to nitpick, but the KJV is not written in Old English. Old English would not be intelligible to any present-day English speakers. The coolest (secular) aspect of the KJV is how its publication in 1611 was actually a major catalyst in standardizing modern English spelling and grammar.
Ofc, Old English was spoken before the Norman Conquest; it's our equivalent of Latin basically.
It's true that the KJV standardized Early Modern English to a large degree; but he meant old simply in the sense archaic, and I do agree. I think the English of 400 years ago had something to it.
