There is OLED and there is LED or QLED
QLED LED is a Samsung marketing term for their LED technology, originally developed by Sony about a decade ago. (maybe 8 years ago)
More or less QLED is a Trademark used by Samsung and is a "twist" on standard LEDs but they make it sound more special and when they trademarked that "QLED" sales took off for the moon with Samsung. More or less Samsung on other brands better LED sets use this technology but may not be able to use the "Trademark" QLED, Samsung owns those specific words. QLED is a marketing term.
When it comes to QLED/LED the HDR standard is what sets TVs apart (local dimming)
OLED is in a class by itself
QLED TVs use quantum dot technology to improve brightness and color. We'll discuss exactly what that means and how QLED compares to other options.

Samsung displays are good as are a lot of others.
Mid to higher priced Sonys are great, good reviews, I think even Consumer Reports, for no other reason than I have one, the middle to higher end Sonys are great.
LED/QLED or OLED each has its place depending on where and how the set will be used. But price does buy higher quality displays if that matters to someone, the typical non discriminating consumer may not know the difference if its not pointed out to them and they may not care if it is.
Love our now few year old Sony 900H ( I believe) the difference to my wife and I in picture quality over 1080p was literally amazing.
The Sony picture on the 900H (at the time) was known for its HDR and Local dimming and to us, until we got used to it, the picture had almost 3d qualities on some material.
