The New International Commentary on the New Testament: The Gospel of John by J. Ramsey Michaels

Eerdmans Critical Commentary: The Gospel and Letters of John, volume 2: The Gospel of John by von Wahlde
The Gospel of John: A Commentary by Frederick Dale Bruner
Anyone who has any of these?
Since before I have one top-rated verse-by-verse commentary from 1953 by a Reformed scholar, one theological paragraph-by-paragraph commentary by a Catholic who also knows a bit about "Gnosticism" from 1978, Hermeneia (the volumes are from 1988 by Ernst Haenchen) and a 2001 monograph about the Jews in the Gospel of Jn by Barnabas Lindars. Plus I have access to the NAC -volume.
The commentary should preferably not be too conservative, but on the other hand not rely on Raymond E. Brown in the Anchor Yale Bible, or Bultmann.
I know the Gk alphabet and I'm learning Gk - I'm going to take several classes in uni.
