If not Aperture, then what are you using on your Mac?

At face value, Aperture sounds like the software I want - a seamless integration with iPhoto.  Easily overlays existing photo's, albums and events and enhances the underwhelming editing softward that is iPhoto.  However, there are so many horror stories about the reliability of this software I am afraid to take the plunge.

So, if not Aperture, then what are you using that functions like Aperture?  What I'm after is the integration concept.  I am testing LR now and so far don't see / know how to export saved images back to iPhoto.  I am having to create a new path into my Pictures folder vs. iPhoto library.  I am reviewing Elements as a more simplistic editing software.  My needs are basic and my desire is to keep things streamlined - all going back to iPhoto for multiple device sync.

Any advice or suggestions?  Thanks
