LG Cinema 3D is great mainly because it is passive tech. But not just that, it improves on its features. Like, flicker free tech. Sure, Vizio has it too but Cinema 3D is certified by TUV and Intertek. Also, Cinema 3D is brighter because of its Light Boost Tech, which makes the images nearly twice as bright. If you're someone with bad eyesight such as myself, this is a great plus!
the glasses are comfortable to wear for hours on end, they are lightweight and effective. also easy to replace in case you lose one or break one.
Unlike the active 3D TVs, Cinema 3D has wide viewing angle. Which means you can watch it from any position, in a wider range. So you can lie back, relax and enjoy some quality 3D!
