GraphicsMagick or ImageMagick

At some point in a web site or web application project you are going to need Photoshop like capabilites and you are going to need them dynamically on the web. This is where packages like GD fall short and packages like ImageMagick nicely fit this bill however recently I was doing some research on ImageMagick something that we use a lot in our shop, ( using php just making command calls to ImageMagick ) and I came across a new project GraphicsMagic or rather fork of the ImageMagick project that not only claims to be faster and be less resource intensive but also claims that its Open Soucre Licensening is valid and the Licensing of ImageMagick is in question or at worst in violation. So as usual I am interested to here from others on this topic.
