I just picked up a sony KBR70R550A because I wanted a large 3D tv upstairs. It's PQ is great, but the black levels and dynamic contrast are much better on the ET5. I just can not get the Sony to look as good as the ET5 in the luminous forest in Avatar. I might return the sony in the hopes Panasonic comes out with a 65" or 70" passive 3D set in 2014. Because I think I am just a fan of Panasonic's panels.
