The one with the best looking picture at the store. Don't connect it to Internet and use your own streaming box (that you trust).

Really I think in store is the way to go. Some "low" and "mid" tvs look identical to me. Some "high end" are meh. Some other "low end" look great. I think it's a bit of a crapshoot. Not sure currently but Samsung QLED used to be rated well but I always thought LG OLED looked worlds better. I've always liked LG OLED although I've heard their firmware has gotten pretty predatorial...
