If you can read instructions, it's not that hard to set these things up. It's just a matter of what you value more. You can spend less than a day setting up the needed *arr software and Plex/Emby/Jellyfin/whatever and have things as you want it, or you can periodically spend time looking for new streaming sites when the one you settled in on finally gets shut down, and meanwhile, you're at the mercy of the site for what's uploaded and in what quality.
If you have it locally hosted, you also don't lose your ability to watch any of the movies you wanted to every time the internet goes out, unlike streaming sites.
Spanish gave us the word machismo, and it also conveniently has its opposite, hembrismo. So, yeah, I'd go with that, myself.
