Whatever has the best panel for the best price, then strap an apple TV (or your choice of NUC) onto it and completely ignore whatever on-board smarts exist.
To turn everything on, I press a button on the Apple TV remote and everything is up and running within five seconds or so (from standby/sleep mode). Powering off the Apple TV also turns off the display and the receiver via HDMI CEC.
Also, Apple‘s streaming services being ever more annoyingly shoved in your face on menu screens.
Some people might not be comfortable with this, or not even trust them to begin with. I personally don't mind paying but there's no way in hell I am providing any personal information to Google.
I have a Chromecast and have never seen an ad.
