I'll 'fess up to being in the whole tone camp as well... The research I've done graphing the individual inharmonicity of groups of strings in pianos has led me to believe that while listening or testing for partial matches between octaves is very precise, (in a micro-sense) it doesn't lead to a more musical tuning. Again, I stress the difference between precision and accuracy. Only by using the ear in the "better or worse" mode to find the best (or least bad!) placement for the octaves will lead to the most musical tuning of that particular instrument. (more accurate placement for octave stretch in the macro-sense.) I think the aural community has responded to the early precision of machine-tunings to come up with methods that match the temperament smoothness - all the while training the technicans' ear to expect, test and appreciate that particular approach - at the expense of beautifully matching single, double and triple octaves.
