The best streaming devices to gift this holiday

Are you a heavy user of Amazon's Prime services? Are you ready to jump into 4K streaming? Then the slightly older $99 Amazon Fire TV is probably your best bet. It streams UHD video just as well as the Roku 4, and more or less matches it in terms of content--from the big players, at least. The user interface is slick, and Amazon's Alexa voice assistant can go head to head with Siri.
