Since many years, I always use Panasonic OLED. The colors are not flashy like Samsung and even though the panel is from LG Display, I prefer the built quality of Panasonic. Their HomeScreen OS is very simple, too and no Google. I still use an Apple TV but one button is only needed to access it.
Things must have been better then, because I have an 18-month-old Panasonic with Android, and I can't get over how buggy it is. I use none of the smart features (it's not connected to a network) and they haven't even got the basics right.
I have a Panasonic-brand sound bar connected, and every time I turn the TV on there's about a 50/50 chance of whether it'll remember the sound bar is there, or whether it'll return to using the (useless) internal speaker. If it does remember the sound bar, it'll work for around ten seconds and then there's a 50/50 chance of it muting itself. Fortunately once you unmute it'll keep working for the remainder of the session.
...unless.
Unless you're playing a game, you put it on pause, and then you come back after a wee while has passed (maybe 10-15 minutes). It seems that if the game doesn't output any sound for a while then the TV will forget the existence of the sound bar again.
For bonus points, and just to prove that not everything is sound-related, the built-in clock has an absurd amount of drift, perhaps 30 minutes a week.
I am certainly not wasting money on another Panasonic.
