Good question. That's a tight horserace. For movies I would go with the M22/500 combo. The deeper/clean bass output of the 500 would make movie watching a more involving experience and because you would likely cross the speakers at 80hz you wouldn't miss any sounds with the M22.
For music. Well I'm biased because IMO its tough to match the performance of a full range balanced floorstander. No phase, blending issues etc. The M60 scores very well in that department. Though for those that prefer more bass in music the 350 makes alot of sense.
