The 6MT really is the bee's knees. I had a 5MT LGT with its standard open front, 50f:50r viscous center, and viscous rear. I now have a 6MT STI with a helical front, 41f:59r DCCD center, and Torsen rear. I
my 6MT and think it's worth every penny as an upgrade if you have the coin.
Seriously, the STI drivetrain is just plain better in every way than the LGT/WRX drivetrain. Shift feel is much better (if you like a mechanical-feeling shifter), traction in the dry is outrageous, traction in the snow is too (with appropriate tires and DCCD settings), the rear bias is nice, DCCD is awesome in any low-traction situation, wheel selection is better with the 5x114.3 hubs, 6th gear is nice on the highway, etc.
Yeah, the 6MT+R180+5x114.3 combo is much tougher than the 5MT+R160+5x100, but it's so much more than that.
IMO the only reason to build a 5MT is it weighs less. If you're serious about weight reduction and want to keep weight down, go with a built 5MT. Even then, if you upgrade the diffs to compare to the standard STI 6MT setups, you'll end up spending significantly more
than you would on an entire (used) 6MT combo!
The equation does change if you have the time, skills, and tools to rebuild your 5MT yourself.
To be fair I've never driven a built 5MT. I'm pretty confident with my judgement of one vs a full 6MT setup though.

Only the STI, Tribeca, 2007-2009 Spec.B, and SVX come/came with the R180. No Outback ever did, at least not in the US.
