I would say that, if you can, pre-order both and keep only one, or check if someone in your area would be interested in either colors and bag, like a family member.
Ursa, really looks like a the dominant colors of grizzly bears, a beautiful rich chocolat neutral, and this is from someone who doesn't like warm colors, but, somehow is fascinated by the ones the TB Crew comes up with.
Wilderness is a true evergreen forest green, so a bold color on its own.
And now, I kind of find myself maybe wanting some things in those two colors, even if I put a moratorium on new colors except Constellation.
