Feature-wise and design-wise LM9600 is one of the best high-end 3D Smart TVs that came out recently. CNET may question the picture quality of this TV but in my opinion, it really depends on your taste. If you prefer plasma, then get a Panasonic but if you will get 3D LED TV get a LG or Sony. I cannot recommend the complicated way to interact with a Samsung TV. They are just too many and not simplified.
Although I have LM9600, I would recommend you check the LG G2 Google TV. If you are looking for the most awesome features in a smartphone this year, get Samsung Galaxy S3. But when it comes to smart TV, get an LG especially the Google TV. The Play Store by Google makes it so simple for my S3 to download apps. Play Store can also do that on your Google TV (LG G2/Sony)
