Giant Badger is one of only two animal companions available to the new UA Beastmaster with access to darkvision (the other is Giant Weasel). That is definitely a consideration depending on the style of game you play.
I suppose if you're going to go by the list of animals provided and not the sidebar guidelines. For my own games, I'll probably be restatting the companion animals so my players know they're all "fair".
