Samsungunc557000 or sony 55 bravia led

I've seen both set up in the Samsung and Sonystyle facilities in New York City. I would give the edge to the Sony based on color hue. However, as with any tv, the set up and calibration are everything. Whether given the Sony the edge was due to correct set up rather then a better technology, is still an open question.

I was under the impression sony used the samsung screen anyway.
