I don't quite understand the issue between you and Sam. However, that article he linked is an informative one that I suggest all that have OLED displays or intending to buy one read for their own benefit.
John,
I watched a couple of Youtube videos that compared the two displays and based on what they said and my own personal philosophy that my old man passed on to me ( If you can afford it then buy what you want as you never want to think about "What if?") Now, he gave me that advice about...
I didn’t want to “what if myself” just to save some money especially knowing the C9 had a better processor and it looked better cosmetically than the B9.
That's one way of looking at it. However, I'm so happy I bought that LG OLED model over TCL 6 Series because I would be second guessing myself forever. If you can afford it then it's best to buy the best you can fit in your budget.
It's my second LG OLED so obviously, I love the picture quality. My first LG OLED replaced my Panny VT "65 while this 55" model replaced my Panny GT 50" model. IMO, both OLED's surpassed those plasma displays.
