My prior TV was a 2013 Samsung LED 1080p F7100, one of their upper middle range TVs.
I always thought it had a good picture, which it does by 2013 standards. A family member has it now and is very happy with it.
The OLED makes it look like trash. Doesn’t matter what is playing - live TV (from an antenna), blu-ray rips via Plex, streaming media (Netflix, et al). I set them up side by side. It was not even close.
With an OLED, black is black, as in the light is turned off. Much darker than a closed LCD shade over an LED light. Also the colors are much richer since they’re generated by the OLEDs and not a LCD shade over an LED light.
All that said, I’m comparing my 3 year old OLED to a 7 year old LED TV.
I have not seriously looked at TVs since I bought my OLED.
From what I’ve read, the new higher end LED & mini-LED TVs have a very, very good picture. Their black levels have improved over the years as has their color fidelity. I don’t think they’re at OLED levels yet, but they might be “good enough.”
The other thing to consider is the room lighting. If the TV will be in a bright, sunny room, then you might be better off with an LED. Current OLEDs are not as bright as LED TVs. If the sun will shine on the screen through a window, the OLED could be hard to see. Obviously not a factor if in a windowless room or watching at night. However, if the room has windows consider what it will it look like when you’re watching live sports in the middle of the afternoon.
To sum up, I love my OLED and would buy it again in a heartbeat. However, it may not be the right TV for everyone. Not trying to be wishy-washy, but everybody’s circumstances are different.
Hope this helps.
Cheers.
