We cut the cord a few years back. I started with Playstation Vue which I really liked but they shut it down. Then I did YouTube TV which I also liked until the price jumped to $70 a month. Right now I have Sling Blue with whatever add on includes TCM, but I rarely watch it so I'm thinking of getting rid of it altogether. I have Amazon prime because I shop there a lot, Netflix because my son pays for it, Hulu/Disney Plus/ESPN, and HBO Max because another son pays for that. I use an over the air antenna for local channels. I have a streaming box and free Peacock premium streaming service from my internet provider, Comcast.
I would say the key to successful cord cutting is getting a good streaming device. When I got Sling it came with a Tivo Live streaming box that was difficult to use and stopped working after 2 months. I have an old 2nd generation Apple TV that was a pain to use and the tiny remote kept getting lost. I also have a Chromecast that I hate with the passion of a thousand burning suns. I don't get great signal in my room and it would constantly drop or buffer forever, or the phone app that controls it would stop working and I'd have to download it all over again. The free box I got from Comcast has a long enough cord I can move it to where it gets a good signal. Our main TV has a Roku box and it works very well. It can show all our streaming services and has its own selection of free programing to choose from too.
