Which is the best Subaru Outback Wagon?

I've got a 2.5i. At first I was pretty disappointed with the "off the line" power, but as it is breaking in, it seems to be actually gaining power and I'm okay with it now. The turbo is probably as fast (or faster) than the 6, but it's still a 4 cylinder when you are at a stop sign. Yes, it's nice to save about 50� a gallon on fuel, also.
