Could somebody give me a run down on the key differences between these two and which one I should pick up?
The Samsung was a much more expensive TV a year ago and can be found on sale online for 1600-1800. The Panasonic is at costco for 1400 so fairly similar in pricing.
I don't care and never use 3D so that factor isn't too important. Picture quality, which TV can handle image retention better are important factors for me.
