Well..finally I got my two set. The second one was the Sony 46EX500.
I got amazed with the PQ after some tweaking from several post of SerialMike and other friends...
In the store I couldn't see any great difference from the EX500 and EX700 (LED)
Being a picky video fan I could see a slight better luminance of the EX700 over the EX500. Both had great quality, nice skin tone...
however both suffered of the opposite sickness of the Samsung. If my Sammy looks to tend to the red spectrum, the Sonys go the opposite a slight greenish tint quite difficult to handle even tweaking hue and White Balance.
I know the bias behind comparing to different set size..but this was my impressions.
The Samsung 6300 is incredibly punchy, brilliant, and colorful. However the flashlights in the corner are visible even not disturbing.
The EX500 is less contrasty...a little pale but for that price can be compared with the EX700 which cost the double at least here in Dominican Rep.
Some people argue that even it seems to have better PQ than the EX700...I can't confirm that since I haven't had enough time to compare them.
Both Sony and Samsung are terrific sets. Something bummer is that EX500 (by far...I just have 4 hours with her) it can NOT play AVI, XVID nur MKV, but MPGs from a USB pendrive nur detect my WD external drive as Samsung did flawlessly reading whatever extension video file I had inside. It was strange since I think I watched a youtube video about EX500 reading XVID.
Anyway I truly recommend these two set knowing that you are not buying a full array LCD, but a non-LED LCD and an Edge-lit ones with its own strength and weakness
Thanks to those who help me to decide..
