LR 5 Beta still lags Aperture 1.0 in terms of general usability. LR's raw processing, noise reduction, sharpening, lens correction, etc. beats the pants off Aperture's, but it fails miserably as a cohesive application.
Andreas, I agree with your comments, but IMO there's some areas where Aperture really needs to make some changes to improve it's workflow. (Keep in mind I come at this from a perspective of processing and editing thousands of images per month.)
- Aperture's implementation for cropping is one of the most frustrating I've ever used, especially after using LR's cropping functions. Crop and straighten need to be combined...they are complementary and having to switch between the two is a big usability issue. And if you don't crop before you straighten the usability issues are even worse. There's no keyboard shortcut for flipping aspect ratio...you are forced to use the mouse to click on a small icon. You can't save custom crop ratios-- having to enter the same custom ratio over and over again is ridiculous. This is database software...it should remember stuff like this. And other quirky behavior -- like changing aspect ratios unexpectedly after you've cropped an image, contributes to the lousy implementation.
- Batch Change is an implementation joke. There's three disparate functions in one dialog. If you neglect to reset the metadata part before you make a name change, you can easily modify metadata in lots of images you didn't intend to. And having to wade through metadata presets to change a couple of fields in a selection of images in incredibly inefficient.
- That leads to "Lift and Stamp". What an archaic, error-prone way to apply edits to group of images! If you have never used LR's Auto-Sync you don't know what you are missing, even with it's drawbacks and quirks. Aperture HAS to come up with a better version of LR's auto-sync so you can easily edit multiple images and apply metadata to multiple images. Keep Lift-and-Stamp around for those who crave it, but PULEEESE gives us a more productive way to do what we need when working with multiple images.
There's more, but you get the point. If Aperture-Whatever-The-Next-Version-Is-Called doesn't address these issues they are badly missing what's required to make it a truly efficient workflow application.
