Aperture vs. Photoshop on sharpening

I'm a long-time Aperture user that just bought CS5 Photoshop. In learning it's capabilities, I discovered how sharpening improves crispness. On the down side, it is a discipline unto itself, and can be complicated.

Sharpening can be done at 1) capture (camera), 2) pre-processing (RAW brick in Aperture, Camera RAW in Photoshop), 3) creatively (sharpening, edge sharpening, and quick brush sharpening in Aperture, numerous ways in Photoshop), and 4) +on export+ (more sharpening for small photos, less for larger photos).

I am still learning the methods used in Photoshop for sharpening. However, I'd rather sharpen in Aperture.

Has anyone had experience using the three sharpening methods in Aperture and know the pros/cons?

Has anyone had experience in operating in both Aperture and Photoshop? Does Aperture come close to producing the same results under most circumstances?

The reason I ask, is I perform most of my adjustments in Aperture, and like the ability to keep all adjustments on one physical image. Need to adjust RAW sharpening? All changes are reapplied and cascaded through to the result. Plus, I don't want a TIFF from Photoshop for every file I sharpen.

My initial tests show Aperture produces good results for small images, but not as smooth and clean as photoshop at 100%.

I realize Photoshop allows much more control in the number of tools, masking, and the nearly limitless number of approaches one may take to sharpen.

But, I'd like to stick to Aperture for the majority of my images.
