best under $1500

[strangerthangs]

so I'm looking to upgrade to a 4K tv after a failed attempt at setting up a projector theater. Part of me doesn't want to go through the whole research process again and just walk into Best Buy getting the best looking TV. I mainly just want something that has great picture quality. Smart features and 3D are only an added bonus not a need. and my budget is trying to stay under $1500. I currently have a vizio 55 inch. I'm not in love with vizio as I used to be so brand wise I'll get whatever as long as it looks nice. I would love slim panels too, the more screen I see the better. size I'm still debating but I wouldn't want to go under 50 inches. Any advice or thoughts would be appreciated!
