I'm my experience it has been the only plugin to help Gimp fill in the space of the advanced features Photoshop users enjoy such as Content Aware Fill.

The Resynthesizer plugin (Heal Selection, Heal Transparency) and Liquid Rescale work well as alternatives to the Content Aware system, in my experience.

Not only that, but these plugins existed years before Adobe implemented these algorithms in Photoshop.
