OP allows you to grab hold of your gantt chart and shape it in a way that no other package has allowed before. You are not tied to the inspector or the outline to create and update plans. This dynamic alone makes OP stand out and takes PM software usability into the world of the Mac UI the way it should be.
Elementary functionality and a few bugs aside, its the best tool I've used in the last ten years for shaping complex programmes. It does not yet cope well with 10,000+ lines and associated details of mature plans, but I'm highly optimistic about is future development.
My single biggest gripe is the application's performance... crikey it's slow on my PowerBook (1.33GHz + 1.5GB)... even with only a few hundred lines in a plan! Merlin wins hands down in this area.
