Good: 

Good brush libraries, allows you to convert between bitmap/vector shapes. Many file formats available.

Bad: 

User interface is not easy to use. Bezier operation is no standard. FAQ's are not enough to solve all questions.

Bottom line:

Working with Zeus Draw is not as easy as one would wish, the user interface needs work ( and it seems there haven't been updates lately) . However application can open many formats and have and extensive set of drawing tools.
