Sure I'd be happy to (only if it is okay with the moderators to technically "derail" my own thread).
I'll start with maybe a couple of possibly controversial opinions:
Godzilla flying with his radioactive fire breath in Godzilla vs. Hedorah and his "kangaroo kick" in Godzilla vs. Megalon are some of the most awesome Godzilla techniques/moves ever (oh and of course, Godzilla blasting Zilla in Godzilla: Final Wars).
I'll unabashedly admit to liking Minilla (partially because of this video
http://www.youtube.com/watch?v=zzickvq_xJA and that the ending to Son Of Godzilla is actually one of the most emotional and heart-warming scenes in a kaiju movie, made possible because of Masaru Satoh's great music

Personal favorite Godzilla suit/animatronic design is the Godzilla Against Mechagodzilla/Godzilla: Tokyo S.O.S.
