Hello Joseph,

Xtreme Pro is a Vector graphics application and would be more analogous to Adobe Illustrator or CorelDraw.

PSP 9 is a raster (also known as bitmap) graphic application. Photoshop is also a raster application. Both have some very basic vector tools, but primarily the programs are for manipulating bitmapped images like photographs.

Xtreme Pro is a drawing application that creates vectors. Some bitmapped graphics effects are possible but not to the extent that PSP and PS can perform.

Xtreme Pro vectors can be used to do things that PSP and PS can do, but require a different approach to achieve the result.

If you want to learn vector graphics then Xtreme Pro is the most affordable and also the most intuitive to learn. IMHO.
