I would avoid anything built into the TV.
- Its starting to be used for spying on you
- The chip they come with are usually not that good unless it's a high end TV.
- They are building ads right into the TV themselves.
I would not connect the TV to the internet and use a external media player. Either a Nvidia shield or an Apple TV is your best bet.
You can also try building a media player yourself using a small computer.
Note - The self made media player will be more limited in terms of apps available, unfortunately, as well as streaming quality from some of the streaming services.
