Now that Adobe has officially shipped Lightroom (as we recently mentioned), the natural question is: which one is better, Lightroom or Aperture? Of course folks have been playing with the Lightroom beta for quite some time, so this is not new question, but Derrick Story over at MacDevCenter posts on two new series by professional photographers writing for O'Reilly comparing the two software packages. He links to the first post Micah Walter's series for the Inside Aperture blog, and to the start of Michael Clark's initial comparison between the two on the corresponding Inside Lightroom blog. Neither has yet revealed their final conclusions, but it should be interesting to see where they both go. On a related note, Macworld podcast 74 features a discussion of the relative merits of the two packages by Rick LePage (as does this earlier post on TUAW).
From what I can tell so far in many of these discussion, the answer to the question is not going to be entirely straightforward, with one package clearly better than the other. It is more likely that the answer will be something like: it depends on what you want your workflow to look like, and how you want to interact with your images. So TUAW readers, what's your take? Which one do you prefer and why?
