I'll tell ya why MOST PEOPLES 2 channel system might be better. For one, they're more likely to get lucky getting 2 speakers setup well than 6 or more!!! You couple that with the "ill-placed/setup" subwoofer situation, mating with the other speakers(amoung the other acoustical challenges), and you've got a "hodgepodge" of compromises going on! Really, most people can't get 2 speakers setup for great sound, let alone multiples.
Also, most multichannel recordings are probably thouroughly mixed together, as opposed to pure 2/3 channel mic recordings. Then you add the need for more processing/decoders, and so on, and you get the idea...
