Summary: I am a football (soccer) photographer and can do anything up to 500 images a game. These need to be sorted, checked, altered and sent out as soon as possible after the game. I have used Lightroom and currently use Lightroom 2 Beta, after I could not get on with the first Aperture. However, Aperture 2 knocks the socks off Lightroom including the new Beta version.
Pros: Allows tethered links, Easy To Install, Easy To Navigate, Powerful, Versatile, Works Well With Other Software
Summary: Aperture 2.0 is extremely intuitive, as most Mac products are. Having recently decided to catalog 30 years worth of color slides and black-and-white negatives, I bought Aperture as well as Photoshop Elements 6. As far as photo correction and project management, Aperture is far easier than Elements. I find the only thing I use Elements for is to invert a negative to a print. After that I import to Aperture and go from there. Highly recommended.
Pros: Easy To Navigate, Fast and Powerful, Great Features
Summary: This is a product from the future. Really unique. Not just RAW converter but great RAW editor also with great photo management capabilities. I am a semi-pro photographer and my workflow is based on Mac. Actually I switched to Mac because of Aperture. After several months I think I can't live anymore without this software. And can't wait to add Viveza as additional component to my bundle.
