    Ease of schematic and pcb creating. BOM creation is not very good as excel templates cannot be used so this becomes a largely manual process. Most of the add-on tools cannot be added regardless of what the instructions say. Following the instructions usually ends in some sort of crash. Import/translation tools never install regardless of the instructions. But, with all of that said KiCad is still the best free alternative to Altium Designer.

    The project is still fresh, but very promising. The developers have spent a lot of time thinking about proper a library file format that avoids problems of current open source EDA suites and will make creating and sharing comprehensive parts libraries easier. It is also much better regarding usability than current alternatives like KiCAD.
