Is NKJV easier for teens to understand than KJV?

I’m looking for a Bible translation that is like KJV but in a way that kids can still understand what’s going on.

For instance, I know Paul’s writing specifically can get pretty tough with the sentence structure but really has some great stuff in it. Does NKJV only alter vocabulary to be more modern English, or does it also reform structure?

I’m open to suggestions other than NKJV, but it will have to be a pretty traditional translation.
