I'll chime in as I had a 2011 Outback with 6 speed manual for 2 years (Mazda 6 was one of the car on the list)
First the good:
The stock pedal spacing is such that you can heal and tow downshift.
It's quiet inside (I love Mazda but sound deadening isnt a strong point)
It rides nice. I routinely make parts runs to SoCal from Vegas and the 7-8 hour round trip is much nicer than my Protege was.
The handling is good for a tall tippy long thing; Last year at a track day I stuck a couple of students in the car for a couple of sighting laps and in a downhill decreasing radius corner (that I entered a bit fast for for a wagon) it was a simple case of trail the brakes, quick opposite lock back on the throttle and on your way. The DSM nanny kicked in just as I finished unwinding the opposite lock, the guys on Outback.org show how to wire a simple modification to work around it. It will also throttle steer through double apex corners. I also helped set up on a stage rally last year and it could be hustled on gravel.
The steering beyond the first 10-15 degrees has very good feed back (I'll get to the issue shortly)
I manage 27 mpg on a 50/50 city highway commute.
It's tackles sand washes and dirt roads very well.
The Bad:
The steering just off center; in order to combat the steering shake issues from the earlier cars Subaru has a lot of preload in the rack, so an inch either side of straight ahead the steering doesn't self center well. Outback.org as a thread on how to back off the preload and get the self centering back.
The shifting is not really a problem but the car is equipped with a damper/dash pot on the clutch pedal. If you are like me and rev match on up shifts it has a tendency to make your timing off. This can be removed and subbed with a set up form a WRX.
On dry pavement beefier sway bars would make it more fun.
The lack of a 100% Nanny defeat button is annoying (again there is a fix)
It's geared rather tall if you want to get aggressive off road.
The Subaru accessories while fitting well are pricey, if you are buying stuff like hitches bite the bullet and get the Subaru ones as they are better than the none size fits all. Did I mention they are pricey.
The touchy feely commercials and all the non car people who own them.
Overall I like mine a lot and even though I could jump in my very sporty Protege for short errands I end up taking the Outback. Our 22yr old son drives a Miata as a daily and even he said it drives nice. Do note I have the Formula 500 and Datsun I vintage race for my hooligan fun, if I didn't perhaps I'd be less fond of the car OR I'd lower the car 2" and fit meaty sway bars and dampers.
