Apophysis and Ultra Fractal produce somewhat different kinds of images - and both are equally well supported by the fractal community. It really comes down to the type of images that you are looking to create and/or sell.

There aren't many Apophysis script writers that would impose limitations to what you can do with an image you have created with the help of their scripts... the one pre-requisite would be that you don't use the raw output of the script - usually a bit of tweaking is necessary to clean up or sharpen the results of a script for the best end result anyways - so that isn't always an issue...

You could always use both programs... grin
