No one has any experience with Aperture 2.0, it was just released today. So thats not a good comparison. Now if you were choosing between Aperture 1.5 and elements, I would say Photoshop elements. I have Aperture, but i almost never use it. I use PS CS3, and then catalogue my photos in iPhoto. Aperture kind of combines both PS and iPhoto; it lets you do some more advanced photo editing, though not to the degree of PS, and also lets you catalogue your photos.
