the new gen car are leaps and bounds over hte old gen in the AWD system . xmode and even the standard programming gets almost rid of the diagonal wheelspin issues plagued with older models. the cars now use the brakes to act like an LSD to get the opposite wheels turning in situations like sand and mud etc
the big issue for you is going to be ride quality. A decently equipped outback (second level up is what i got) with eyesight and power liftgate (my only two required options), no leather, is the same price as the forester 3rd model up) with xmode (xmode is standard on all outbacks), the HK radio (standard one super sucks, and ugly) and leather (have to have leather to get xmode)
the forester is a horrible ride compared to the outback. i drove them back to back and we were instantly turned off. they haev the same ground clearance, approach and dep angles are a bit different, but with the refinements in the outback (quieter, smoother, more cargo area, built in cargo racks if its something you want, more default features, dual climate control on the lower models) id get the outback. I actually went in there with all intentions of getting a forester too....if it matters.
