I think perhaps the OP -and certainly I- don't look at the 6-cyl. solution as "far-more-satisfying"-akka. I use the Tagalog suffix that means "-for you only." Some of us are fond of the simplicity and efficiency of 4-bangers. Long-term reliability? I've seen no data demonstrating that. Better acceleration I'll give you, but we drove the 2.5i Outback Limited two weeks ago, and the acceleration was quite adequate, and the noise was OK.To the best of my knowledge, there have not been any HG issues with Subie's 6-cylinder engines, so by opening up your wallet and opting for the far-more-satisfying 3.6R, you are likely to wind up with better reliability as well as much better acceleration and a lower interior noise level.
And, for those who are not fans of the CVT, you would get a "conventional" 5-speed automatic trans if you opt for the 3.6R.
The question remains, has SOA managed to address the HG problem in recent years? This appears to be mostly an issue that crops up in well-used cars, so only time will tell.
