I'm also in this very same boat. I have spent countless hours at BB and reading reviews over the P-Series, X850D, and KS8000. I was sure I was going to get the 2016 Vizio P-Series when it was released over any other TV given its specs on paper. When I was finally standing in front of a P75 and watching the Dark Knight on Blu-Ray in the Magnolia room at BB I was extremely disappointed. I looked at the Samsung sitting right next to it and it was night and day. The Samsung's picture was sooooo much better it was ridiculous. Messing with all the settings on the Vizio couldn't even come close to the Samsungs pic. Now after reading how much better the Samsung converts 480,720,etc. than the Vizio I am pretty much sold on the Samsung. I would say 90% of my viewing is going to be from DirecTV (Sports, movies, reality shows,etc.). I really wanted the Vizio but now that the Samsung is just $200 more through Costco I think I am going to pull the trigger on that next weekend unless I am really missing something here about the Vizio?
