I'd check the warranty duration (1 year? Kidding?) I see from a table one is edge lit and the other FALD.

I think this one is best picked by you seeing both sets. My view of Samsung's Smart TV design is they botched it. Count on later adding some external box as well as receiver for audio work.
Anyone have any feedback on the differences in performance?
