Video speaker showdown: Which is best -- Amazon, Google or Facebook?

USA TODAY's Jefferson Graham takes a look at three new connected speakers that all have video features. Amazon has enlarged and enhanced its Echo Show device, which brings video to its line of smart speaker, Google counters with the Home Hub, adding video to the Home line of speakers, and Facebook is in there as well, with its controversial Portal video speaker. We've taken all for intensive test drives. Which one is for you? The Google speaker, ($149, on sale for $99 during Black Friday sales) is our all-around favorite of the trio because it does more than the others.
