You didn't specify 50mm. He was talking about the 35, you suggested the afd version, which would lead one to think you're talking about a 35mm 1.4 AFD, which has never been produced. Just saying "get the nikkor afd 1.4" could be referring to more than just the 50mm.
As for the 50 1.4 afd, it's a great lens, but it's a little slow in focusing and as they wear from usage, can get clunky and noisy (I own one and use the shit out of it).
