Just bought a Amazon Fire TV 50", is it as good as a Sony or Samsung, no but for $300 its pretty good. I'm able to stream all the services I use, Prime, Hulu, Netflix, Peacock, Youtube and Tubi. Picture and Sound are better then my old Viso. My biggest gripe is the 4' power cord. Got it on a 3' stand so I could barely reach the power strip. Can't believe how light these things are getting. Weighs a fraction of the 32' I bought over 10 years ago.

If your looking to buy a higher end model I'd recommend looking on youtube, there are all sorts of channels dedicated to reviewing the different makes and models.
