I'd posted a few weeks ago about getting lucky on a 55" TCL 6 series for my parents' Christmas present. The build date is September 2018. I consider it a winner of the panel lottery as there is almost no DSE or banding. The panel integrity on this particular TCL is not far from my 75" Sony Z9D (yes, of course the Sony outdoes the TCL in several other areas).
Pros: Test content fares well and movies looks great as I cannot find a single viewable flaw in real-world usage. Very bright! High contrast! The ROKU system is great and snappy! It's very light, even with though it's FALD (my Sony weighs 99.4 lbs). PRICE!!
Cons: The upscaling is very poor compared to Sony X1E processing. The color gradient is not as smooth and natural (8-bit panel?). The speakers are no better than average computer speakers.
Again, this TCL is the best bang for the buck for any modern-era TV I've ever seen. Wishing the same luck to all others who purchase this model.
