I'm getting into Duff's textbook (see thread in this forum if interested) and I got A Greek Grammar of the New Testament and Other Early Christian Literature by Blass, DeBrunner and Funk. It is fascinating reading so far. I have some experience in Latin so it is making sense although it is still somewhat above my head.
Is this, in fact, the best grammar for NT Greek? I also own Smyth's Greek Grammar, but my impression is that Smyth is better for other earlier forms of Greek. (Forms which I will approach at a later date.)
Just looking for experiences, comparison and impressions. Bring it on.
