Let me put it like this. I love the KJV and it is all I use. The other versions I have come in contact with have a softer way about them and they seem too me to be watered down. I am sorry if that offends you. If you like them that is fine with me but I have my own preference.
Although I no longer use the KJV as my main Bible version, as I prefer the original Hebrew and Greek, I do find that its textual basis is some some important verses, like 1 Timothy 3:16, which is the clearest verse for the Deity of Jesus Christ, and His entrance into humanity; and 1 John 5:7, the clearest verse for the Holy Trinity. However, it is weak in some areas of important texts, like the rendering of the Greek text into English, for Titus 2:13, and 2 Peter 2:1, where the Greek speaks of only one Person, the Lord Jesus Christ, the KJV leaves it open to the possibility of two Persons being meant. That said, I believe that John 1:18 in some modern versions have it right, where they use "θεός", instead of "υἱός", which is yet another important testimony for the Deity of Jesus Christ, and His equality to the Father, as both Persons are called "θεός", without the use of the definite article in the Greek.
