What's the difference? Genuine Fractals 5 and GF Print Pro 5

[Ruffio]

Ok, I have looked at their website, trying to determine the differences and if the Print Pro version would be worth the increased cost. I really couldn't see much. CMYK support for the Print Pro version.

What are the other differences besides the obvious--cost? What have been your experiences using this plugin? I'm going to buy one. I just don't know which. TIA!

I use genuine fractals pro solely for enlarging when necessary. I find it does a very good job, with some images visibly better than sizing in PS.
