What about Apple tv or the Amazon stick?
I just mentioned the two I did, as I find Chromecast to be a first class concept beautifully thought out an executed, with excellent ergonomics. It, by slight of hand, connects your receiver or TV to your router, with the mobile device just acting as controller. It is really elegant engineering. The downsides are that you have to use the Chrome browser, and the site you want to stream has to support it.
I mentioned ROKU as it is consistently and widely acclaimed to be the best streamer at the moment. An Amazon Firestick is certainly an alternative.
If you get Apple TV, I think you will likely need a streamer, as I'm suspicious that your TV is deficient as a streamer. So for sure whatever you do, make sure your streaming device is connected to your receiver and NOT the TV.
Again, you must not neglect your homes Ethernet infrastructure. The technology tries to hide deficiencies, by downgrading your stream without you knowing it if it is deficient.
Have you done Internet speed tests at the location where your stream? If not you should. My experience is that most homes are severely deficient in that regard.
I live on a circle where four homes were built be the same builder over the last two years. My home is the only one with a properly engineered Ethernet infrastructure, not withstanding the fact that one of the homes we specked for a couple with high powered HT jobs. The other homes are deficient, and not just the Ethernet.
I should state that most of our streaming is via HTPCs. All have Chromecast, and that is the only streamer in the family room.
In the theater there are two computers, a DAW and HTPC. That is the only one of the three systems that has eARC, and I do stream Netflix, Amazon prime and the Berlin Philharmonic Digital Concert Hall from the TV via eARC.
I just have an antipathy to what I call hunt and peck streamers. To my mind an HTPC is still the best way to stream most programs, and gives you an exponentially larger range of options in programs than any streamer. It versatility from a full size radio linked keyboard is far more convenient and quicker, than any streamer with a hunt and peck remote.
