I don't have the RNWT to compare, but I think a couple of posters on here are working on doing a side by side presentation so we can see the difference.
What I find very annoying is the use of the word "spurious" for most of these verses, yes in a number of cases we do know they are deliberate later additions, but this is not necessarily true of all.
And what it fosters is the idea that there is some kind of "genuine" or reliable text, which as Prof. Ehrman clearly shows is simply not the case.
All we have is copies of many generations of copies, many done by amateur copyists not familiar with the language they were copying quite often, the oldest we have is about 150 years after the originals, so Textual Critics can only take a guess at what was originally written.
And hence, the Master Texts are simply educated guesses. We have nothing that we can be sure is not spurious.
As Bart Ehrmann says, there are more errors in the manuscripts than there are words in the new Testament.
And yet the WT wants you to lay down your life, or worse, the life of one of your children, based on their weird interpretation of doubtfull words that have no Provenance.
Crazy.
