No English translation can be the basis of the Bible. Only the Koine Greek, and Hebrew and the Greek in the Septuagint. Those are the only sources to compare.
I used to be obsessed with comparing translations. Then I learned Greek and Hebrew, got some tools like lexicons, exegetical guides and commentaries based on Greek and Hebrew. I can figure out a lot of issues, because some things don't translate well into English. Word order doesn't translate well from Greek, because Greek, like German uses noun and adjectival cases. Verbs are more important for their aspect, rather than linear time, as we use in English. Participles are minor in all the modern languages I have studied. I used my second year French grammar to remind myself of the parts of speech, when I looked for participles, they didn't exist in that compressive case. In Greek, participles are very important, and how you translate them. A lot of these subtle issues are not apparent in a translation into the English language.
Comparing English manuscripts doesn't tell you anything. When I took second year seminary Greek, I took it from Dr. Bill Mounce. He has been on almost every translation committee in modern times. He quit the ESV, because it was just a reattempt of the KJV. It had been billed as a "fresh and exciting new translation," but he and his father, also a Greek scholar, realized the first few sessions that ESV was just another KJV translation. From Early Modern English to Contemporary English! He has also written an often used 1st year seminary Greek text book. I used it in seminary. He had so much insight and understanding into Greek. So many details and stories about Greek word usage. He also has a morphology which has every single word in the Greek NT, and the cases, if it is a noun or adjective, or conjugation if it is a verb. Sitting in a Bible study with some English translations is simply never going to come close to understanding and using the original languages.
I always feel so blessed that God gave me the privilege of learning Koine Greek and Biblical Hebrew. If you want to "put in the work" then learn Greek and Hebrew, you will be on the right track. The languages the Bible was written in!
