There are three primary versions of the Greek text for the New Testament. The one I think is the best most accurate version is called Critical Text, and is favored by most modern scholars. Many of the modern translations are based on it, including the NASB, the NIV, the NET, and the LEB. Next we have the Majority Text, or Byzantine Text and the WEB is based on it. Finally we have the TR and the KJV and NKJV are based on it. Advocates for all three claim theirs is the best and the others are just awful corruptions of God's word. The true is all three serve God's purpose, and they teach the same gospel.
Your best bet is to adopt the NKJV, but when studying a passage, compare with the WEB and NASB versions.
