Nobody is going to tell you which one to buy because needs and uses are different for everyone. If you are a gamer, you might want to pick a specific model (not a series) and then go that forum and ask about lag times etc. If you're mostly watch tv/movies, then one with a good implementation of motion interpolation may be what you want. I'm not a fan of smart tv's. I think one is better off with a blu-ray player that has integrated WiFi than having that feature built-in to the tv (less things to go wrong). Where ever you buy your tv, make sure you understand their return policy in case you don't like it after a couple of weeks.
