It's not connected to the internet, it doesn't show me any ads. When I (rarely) turn it on with its remote it boots to the last used input. If I turn it on through my set-top box, it boots to the box's input. The box can control the TV's sound volume with its own remote, and the TV has an "ambient light sensor" which allows it to adjust to ambient light. I never need the tv's remote.
It's a 65" TV which cost less than my 32" monitor. Sure, the colors aren't as precise, but I don't use it for phot editing, and delta E is actually very low. The sound is good enough to not have to turn on my stereo, and I don't need to turn it up to 11 to understand voices (my dell has 0 sound). For watching mostly voice-based content (think talk-shows, comedies), it's great.
The company I work for regularly buys "dumb" screens to be used as "signage" (it's part of what we do). I've seen those screens. The image isn't any better than my TCL, but they cost 3-4 times as much. Sure, they're supposed to run all-day-long for multiple years and burn your retinas in 0.2 seconds flat, but I only watch my tv a few hours a week tops and not in direct sunlight.
So I'm a very happy camper. An equivalent dumb TV wouldn't be a noticeable improvement for my use case.
