I have a Samsung QLED. I *love* the set, but have one real complaint. The Samsung apps suck. They freeze all the time. I have to get up and "reboot the TV," that is unplug it for about ten seconds, probably every other day on average.
I also have a Sony TV with Android apps. Those work much better (for me, at least), and there are more of them. For example, if I want to watch MLS soccer from Kansas City (or certainly NHL games from STL), I can only watch them on the Bally Sports App, meaning I can only watch on my Sony TV.
My VPN service also doesn't have a Samsung app, meaning I have to go to my Sony to do things like watch British broadcasts of World Cup soccer games.
The crappy Samsung apps aside, Samsung makes outstanding televisions.
