I don't know how you got the idea that Nestle-Aland or the UBS critical texts are any different from Westcott & Hort or Nestle. There is not one iota of difference. So let's put this fallacy to rest with one example, which actually has doctrinal significance (1 Timothy 3:16). You will note that all these critical texts are IDENTICAL, so you might as well admit that Westcott and Hort rule the roost.
I will also compare the Traditional Text, and your repetition of the fallacy that the KJV is based on a handful of manuscripts will be seen to be totally false. Indeed the Traditional Text is supported by 95-99% of all Greek manuscripts in existence (over 5,000).

The reason I have bolded "os" and "Theos" is because the corrupt manuscripts have "who" or "which" instead of "God". To Socinians, Arians and Unitarians, that is very significant, since they always say "Where is Jesus called 'God' in the New Testament?"
