I work in the film industry - doing mostly 3DST film titles and VFX. I've really, really appreciated the forums here as I've been putting together a HT. Thought I'd share a couple bits of info from my field that may be helpful. Should be noted that this is certainly not meant to "authoritative", 3DST is still new and being figured out in our industry too …
Re Passive vs Active: At the moment there isn't really a standard in Post Production. Choice of format is usually based on two criteria:
1. The use. For long term viewing (i.e all day) like editing or 3D conversion QC sessions (of the 3DST only, not the overall picture quality) the choice is usually Passive. For short viewing sessions like final QC and "finishing" sessions, the choice is usually Active.
2. The user. Different people's eyes/brain perceive/process visual information in different ways ...
Some people have sharper vision for resolution, their brains tend to process more detail into "image fusion". For this group the interlaced nature of passive 3D may really stick out and bother them.
Other people have sharper "persistence of vision", i.e. their mental "refresh rate" is slightly quicker. For this group active 3D TV's will have a very noticeable and distracting flicker.
Interestingly most people seem to have one or the other "sharper" vision, not both.
For your home 3DTV I would suggest a simply viewing test of each 3DTV format (active and passive), and, whichever looks good to you then go with it. I would also suggest your view test last at least 10 minutes.
Re future of 3DTV's: This technology is still in it's infancy. There are two immanent advances that will essentially even the playing field re Passive vs Active question in the next few years.
4K will make Passive a "visually" true full HD/2K 3D format on screens smaller than 80" or 90".
Faster refresh rates will eliminate the flicker on Active 3D. Somewhere between 180hz and 192hz is a sweet spot where no-one will see a flicker. (Currently most theatrical active 3D systems use refresh rates of 140 or higher, which is why you hear "fewer" flicker complaints.)
Both of these advancements will also help reduce or eliminate ghosting. (From what I've read/heard "good" glasses-less 3DTV is still quite a ways off.)
