Actually I have been using both Aperture 2 and LR 3 Beta for a few days now. Both programs are great, but I find Lightroom loads a lot quicker, maybe because it's running at 64-bit under Snow Leopard. And I also like the gray/charcoal background, and all the editing tools are there. In Aperture, some of the tools are hidden and you have to manually to have it shown.
That said, I like how Aperture integrates with iPhoto (and Vice versa), the way it manages the library, and you can easily order photo books upload it mobileme gallery. If Apple would improve on SPEED and make all the editing tools more readily available, I'll definitely go with Aperture. But at this point, like others have said, it's a personal preference. I think I'll play with it some more and decide. Thank you for all the inputs.
