I do t know the specific differences but from what I’m learning the systems are mostly the same across brands. I was gifted a Roku and this is my first experience streaming. What I can say is I LOVE IT! Cable customer since early ‘90. Was afraid to change because of well change. At $240 a month for cable package I decided to try Roku on an upstairs tv. Now I have a Roku TV on the patio—- love it too! Also have a stick on the 75 inch downstairs and we cut the cable cord. Roku is easy, reliable and opens the streaming experience easily.
