The Textus Receptus is the traditional Orthodox Greek bible, as passed down from Byzantine copyist through Byzantine copyist (https://en.wikipedia.org/wiki/By… ), into one particular manuscript that Erasmus got hold of, and missing one page that Erasmus translated from the Vulgate. It is distinguished for being the first widely disseminated Greek text in the age of printing. It is the authoritative text of the Orthodox church, but noone involved was making an attempt to reconstruct the original text.
Textual critics, who are trying to reconstruct the original text, tend to prefer the Alexandrian type, at least for the Gospels. But this is reconstruction, and reconstruction based on sometimes subjective criteria (which nonetheless make sense when you think about them.)
