A:Answer While they both offer 8 gb of internal memory the Fire TV has USB 3.0 and an SD slot for extra storage. Also the Fire TV has an HDMI port, an ethernet port, and an optical audio port for home theater set up. And the biggest difference between the Fire tv and the fire stick is it's Quad core processor and 2 gb of RAM to make it available for 4K streaming. The fire stick is great and they both have the same user interface. The reason for the great success of the fire stick is it's mobility. Very easy to take anywhere with you in hotels, or dorm rooms. If you're looking for something easy and quick the fire stick is probably better for you, but if you want want the 4K and 3D experiences then the Fire TV is right for you.
