how well does unlimited data work with streaming video

I have been using Verizon unlimited for 3 months using about 200 gb a month watching Netflix and Prime. I have had buffering a few times but not enough to cause a real problem, found it works best with a HDMI cable from my computer to my TV,google did an update this summer and casting with chromecast from phone is not working at present, but I read that it is being fixed with the next google update, We will see. Hope this helps (you mileage may vary )
