There's an AI response here, because I can't be bothered doing a lot of research and don't know enough to make a realistic contribution anyway.
The two main takeaways I received from this were -
Greater Antiquity: The Critical Text incorporates manuscripts dating from the 2nd to 4th centuries (like Codices Sinaiticus, Vaticanus, and early papyri). By contrast, the Received Text relies on a handful of relatively late, medieval Byzantine manuscripts (primarily from the 12th to 16th centuries).
Minor differences - Despite these differences, textual scholars generally agree that the Critical Text and the Received Text share an identical meaning and wording 98% to 99% of the time, as the vast majority of variants are minor spelling or word-order differences.
Other issues according to the item are correction of copyist errors and and continuing scholarly refinement.
When there are differences between Bible translations, I think we need to look at the reason a translation was made in the first place.
I remember my (Presbyterian) pastor who knew his stuff saying he probably had more issues with the NIV than the Good News version. Yet the Good News version was intended for people for whom English was a second language, and was kept "simple" for that reason.
He did say he thought the JB Phillips translation of the New Testament was very well done.
I'm Catholic now and unfortunately I don't read the Bible anywhere near as much as I used to when I was Protestant, which would probably not be uncommon. But despite the pastor's comment about the NIV version, I probably read that version more than any other. The book fell apart in the end.
I have been very slowly wading through the Douay-Rheims version with its slightly archaic language. It was the (English) Catholic Bible at the same time the Protestants were moving towards the King James.
In the end they all say pretty much the same thing.
