IMO the only use for an SUV is if you postively need 3rd row seating and off-road capability, which is possible if you're a skiing family and your kids want to bring friends and your cabin is at the end of a long dirt road. Otherwise, I think they are overweight and generally misused. The extra weight increases your odds of sliding off the road, and also rolling over.
That said, I am a big fan of the Outback. I really don't like the Forrester. It's the wannabe Outback, and I don't like the look of it. And I think it's a favorite among lesbians. "Not that there's anything wrong with that" - it's just not the image I'm after.
I would love an Outback XT or Legacy GT Wagon, but I would definitely chip that thing as soon as I got it. The stock fuel consumption is abysmal. I believe there are chips/flashes out there that allow you to change power maps on the fly - like from economy to sport or valet or whatever. I'd research that heavily.
I'd probably go for the turbo over the 6cyl because turbos afford more flexibility with software. For example, I could chip my VW Passat and get 38hp more out of the 1.8 liter turbo engine, taking it to 208hp. The V6 can only get like a 12hp gain from a chip. Speaking of VW, you might also consider a Passat GLS wagon with 4-motion (all wheel drive). But if you need a little extra ground clearance, the Outback wins. Long term cost of ownership on the Outback might be a bit lower too, but if you buy cars every 75-100k miles, it's probably a wash. Very happy with my Passat, very comfortable ride and the 1.8T in stock trim has good pep. But my next car will probably be an Outback.
One drawback to a turbo is having to buy premium gas - which really stings right now. But I think the suby H6 and VW V6 need premium too...?
