My favorite TV of all time was a 65" Panasonic plasma.

4k OLED looks really good in dark scenes, but something about turning that plasma up to its full 800 watt+ vivid mode is a completely different universe.

Practically unusable during the summer in Texas though. The efficiency is really bad and you essentially need a custom hvac solution if you want to put it in a proper "theater" room. The noises it made in high brightness scenes were also a bit distracting. It had to move a lot of power very quickly.
