It seems to me that if you truly believed that Lightroom outperformed Aperture on almost every level, you wouldn't be hanging around in the Apple Aperture forum. When I ditch a bad tool, that's it — I move on.
I use both of these apps constantly. Lightroom has more powerful image adjustment tools — particularly the basic adjustments, and the way that you can push and pull dynamic range, restore overexposure, brighten shadows etc. Great for fixing poorly exposed photos. I never worry about sharpening or lens corrections or noise reductions, but I admit that Aperture needs improvement here. In terms of user interface and asset management, however, Lightroom is a poorly designed, frustrating relic, almost laughable in its backwards thinking. It wouldn't take much to get Aperture to catch up with Lightroom's image adjustment prowess, but it would take a change of product managers and a complete overhaul to fix Lightroom's asset management features and user interface. Apple will improve Aperture's image adjustment tools, but the Lightroom team refuses to even admit that Lightroom's modular approach is archaic and clumsy, and that its interface is a cluttered, blinking mess — a sad blight upon otherwise splendid Camera Raw technology — so there's little hope that Lightroom will ever match Aperture in this regard.
Worst of all, anyone who thinks Adobe won't start charging a subscription fee to use Lightroom is living in denial.
