So, all things being equal, I prefer to read from my Robinson-Pierpont or my Trinitarian Bible Society Textus Receptus. I also dig my editions with facing Modern Greek versions.
Wilbur M Pickering has an interesting take on a specific family of Byzantine type manuscripts. His differs from Robinson-Peirpont in about 1500 places, most minute. He hasn't published it yet, but, according to some recent emails, he's looking into it. The reason I mention this is because in an email back and forth, he sent me an overview of the general epistles, and from his collations so far of family 35 or Kr for Von Soden's Classification, hes come across a number of manuscripts which show NO VARIATION when comparing NT book by NT book. On top of this, there seems to be a very careful "transmission" of the family of byzantine manuscripts. Let me know what you think. Here's his website http://www.walkinhiscommandments.com/
His GNT is available here as well in PDF form.
I know this is more of a "textual critical" discussion, but because its Koine Greek, I think it fits here.
