I am teaching introductory Greek this year, so I better read the Greek Text. I was appalled to find out that my UBS 5ed. had no Mat. 1:1-18, so I had to use Nestle/Aland 28ed to cover that. I am back to UBS and up to date, for now.
I am also using A New reader's Lexicon of the Greek New Testament to help me read.
Hope this helps.
