Streaming is good, but not without its cons too. One thing you might find leaving a cable/TV provider is that the collection of streaming app/services needed may end up exceeding the cost you were paying, depending on your wants and needs, due to the scattered nature, right now, of streaming services. If a number of those channels you depend on with Xfinity cable are important, then streaming the Xfinity app with a streaming device (such as Roku) and dumping their boxes might be a cheaper/better option, but again that depends on what you want/need for the channels. Ad free usually means older shows or reruns frequently of the same episodes and, usually, some type of subscription is needed to watch newer stuff or recently released episodes/movies, etc and live services are a bit all over the place and hit and miss when it comes to certain channels in how well they are supported by the owners of the app/channels.
One of my biggest frustrations with streaming is the lack of cloud recording with a number of apps, which is why I stayed with cable service and use streaming combined with their cloud services, especially for live events, such as sports games.
