I have used all photosuite packages and found them to be very good. However I don't feel that creator 9 is worth moving to. I find it to be very slow, I am using an AMD 4600 x2 Chip with 3gb of ram. I added another 1gb as the program kept crashing on me and telling me I didn't have enough memory for opening photos. It still does this after a chip upgrade and an extra gb of Ram.
The package I used before was creator 8 now that was a different story, very fast never an error message and I created many movie projects.
