From these specs, I would choose one of the lightest two, and of those two I would choose the Toyo because the two pound weight penalty is worth the higher UTQG ratings. Throw in the great reviews on the Toyo and you have a winner. I believe in the stock 225/65-17 size the Toyo comes in at 30#.
Had I gone with an all-terrain, I would have chosen the stock size Toyo. Instead, I ended up with a stock size Nokian Encompass all weather tire because I'm more interested in winter performance from the Subaru; the Nokian has aramid sidewalls for durability in the type of off-roading we might take the Subaru on, our pickup has KO2's for serious off-roading, the type an Outback would not be able to do no matter what tires or mods you do to it. As a bonus, the Nokians come in at 26#, same as the stock Yokos, so no surprise the fuel economy has remained the same.
For the OP, the G015's that come on the Wilderness are decent tires, you might consider saving your $800+ and get your money's worth out of them before replacing them. I got 36K miles from the stock Yokos that came on our Outback.
