Cut the cord 4 years ago, and primarily use Roku devices. Right now the Roku Streaming Stick+ is about the best value to performance ratio for Roku devices, have not seen any lag or buffering issues. Also, 4K content comes through no problem.
Key to this lifestyle is to try and get internet through fiber if possible, or spend a bit more to get stability and more mbs. Had loads of issues with cable internet in my area, was a constant speed dial to the provider every two weeks or so. Paying for 100 mbs, realizing only about 15 and down to 5 at some points. Total garbage. Getting 300 over WiFi now with the fiber, same price point (not an introductory either). Realize this isn't available in most places though.
Anyways, we will never look back. Counting all subscriptions (Netflix, Hulu, Sling, etc) all in we are about 50% cheaper than the similar packages offered by dish or cable. We were already paying for Netflix anyway. Interruptions in service are rare, and no more than cable outages (or thunderstorms when we had DirecTV).
Bundles are of no use to us, we have no need for a landline. Was also getting sick of the "threaten to quit" cycle to lower the rate every so often. With this, I can quit with a click, and resume with the same whenever I want.
