Not sure when he wrote this, other than in the last 6 months, but Robert Edwards looks at Aperture or Lightroom = Neither:

I'm not suggesting there isn't a use or market for Aperture and Lightroom. Certainly their sales figures suggest otherwise. What I am stating is neither Aperture or Lightroom is the panacea digital photographers want them to be. At present no single application is going to successfully do it all for you. There is no Swiss Army Knife software for photographers. By the way have you ever tried using a Swiss Army Knife in preference of a real tool?
