There are SO many reasons the NWT is superior, that I'll start with the most obviuos: God's Name
Strange, I read the nwt sevral times as a jw, and can't recall seeing yahweh in there once. I know jehovah is supposedly the modern way to write yahweh, but YHWH wouldn't translate as jehovah, would it? Also, I wonder how many times YHWH appeared in the original new testament writings?
The nwt was translated in such a way as to back up jw doctrines, as in John 1:1, Luke 23:43 - we all know why they put the comma where they did.
MAD said there are many reasons why the nwt is superior. I can't think of one.
