Unfortunatly, this is a personel preference issue, not a "best" issue
All the brands you mention are well respected names, put out a solid product, and each have their fans and detractors.
The only way to find out what's "best for you" is to subject yourself to the tedium of listening for yourself and making a personal judgment unless, of course, you want to base it on popularity and, in that case, just post a poll here and go for the one with the most votes.
I do, however, concur with the guy who suggested you base your decision on music, not movies, when you embark on that heinous mission. Many systems that sound good with movies suck on music, but I've never heard of a system that sounded good on music and sucked on movies.
