I got to see the VT60 next to the Samsung 8500. We put the 8500 in Movie mode and the VT60 in THX Bright mode. My wife, two Magnolia guys (who were pretty excited about the just-installed VT60) and myself, all gave the overall PQ edge to the 8500.
The 8500 showed more detail and pop with what looked like very similar black levels (as best as could be determined in the subdued Magnolia lighting). We all wanted to see how the brightness compared too. Again, to everyone there, the 8500 clearly had more headroom.
I did notice the VT60 displayed better shadow detail and there were some subtle differences in skin tones, but this was a bit harder to nail down given the stylized movie they were playing (one of the Hobbit movies).
Keep in mind that neither panel was calibrated, so these are just initial impressions. I honestly thought the two would look closer in overall PQ aspects. I'm still weighing the ZT60 vs the 8500, and this pushed me a bit closer to the 8500, but again, this just an initial impression.
