My main is a Sony KDL-50W800C. That's a 50in Android TV. This is the best one in the house and has a 5.1 Onkyo system connected to it using HDMI ARC. Built in Chromecast and installed VLC for local streaming.
My secondary in the main living room is an old, dumb Samsung UN40C5000QF. That's a 40in. I have an RPi 3 connected to it with Kodi for local streaming from the NAS and Comcast gave us for a free one of their new devices (Xfinity Flex) for other streaming services like Tubi, Pluto, etc. Also have an older Chromecast attached to it.
The most recent addition is a cheap HiSense in the bedroom. It's 32in and is an Android TV. My main complaint with it is the built in WiFi is so fucking horrible that you can't even use it for anything. It disconnects and is horribly slow. So I had to run a cable to it. Second complaint is the power cord is hard wired in. Otherwise, it's not a bad TV. It's even got a cool feature we use a lot that allows you to continue playing audio with the screen off.
For actual TV channels, I refuse to pay for garbage I don't want (like MTV, Lifetime and TLC) so we just use an antenna for OTA channels. It's split to directly wire into the Samsung and then into an HD Homerun box for streaming to the Android TVs. Works pretty well.
