Just a case of different "horses for courses". MMG's, or maybe even planars in general, are the wrong horse for your course. Personally, I think everyone should have both a planar and a box, like having an electric and acoustic guitar, but if you can only have one, then you just pick the one that does it for you.
A rematch with 3.6's, with the right amp and a sub properly dialed in, might prove diffent results.
