Very surprising - I have both the MK012 and MC930, I'm almost certain that I have a darker MK012 and a MC930 with more top.
MC930 have definitely a more linear off axis response which makes the stereo-imaging better.
Under all circumstances - interesting shootout; three good candidates for Akk Guit recording; all would do well. It is still more a question of instrument and mic placement in my book.
