re: Speed of internet needed to cut the cord

Thanks for the help. I don't upload a lot. An occasional movie maybe here and there maybe, but for most part just browse internet and checking email etc. Not into heavy gaming or using anything that I'd think would take up a lot of bandwidth. So if I went with the cheapest option it sounds like I would be ok. I have one firestick and an apple TV already and am about to get a google chromecast. Are any of these three better than others to stream, or am I better off going with a roku or other option?
