There was another member who kept insisting that plasma at its peak was the best screen tech yet made. Having solid experience of both over many years, I have to keep pointing out that this isn't true. I loved my plasma sets back in the day, but am agnostic in terms of screen tech. It could be powered by carrots for all I care, as long as it produces the (best) goods. The more realistic levels of brightness in an OLED (and other new screen types) can take a little getting used to, but it didn't take me long - and having done so, the two plasma sets we still have look pretty flat and dull in comparison - a bit like looking at a photo taken many years ago in comparison with one from yesterday.
I genuinely see nothing that any of our three plasmas did/does as well as my present OLED (including black depth, smoothness of motion and the feeling of looking 'through' the screen into the image), and that's before you add 4k and HDR into the mix.
I suspect I've done this to death, so will now shut my trap!
