I swapped my Kuros for a Sony W905, none of the Panny or Samsungs were any good imho.
And I am a huge Panasonic display fan, still think some of the commercial plasmas looked better than the Pioneers in many ways.
The Sony is pretty damed good, but not as good as the Kuro, I just wanted a smaller, neater looking screen with features built in.
I am pleased with it, but am the first to admit they are not as good as a decent plasma.
OLED will be my next display, but still a few issues with them at the moment.
