For CAMEO, it's not only the ease of use, it's versatility, its communicability, but Rhapsody is the worst tool I've ever used. It is very difficult, not user-friendly, and very expensive. It works only with its IBM counterparts. SPARX Enterprise Architecture is very easy to use, but it's limited. It gives you an idea of how your model is developing, so this feature helps maintain integrity or correctness of system models. It's really a good feature to have. You've got to have the simulation toolkit installed to be able to do that, and that works really well. The MagicDraw or CAMEO system is good on its own, but it should be integrated and should come out of the box with the simulation toolkit because there are some things you can't do without it, making it very difficult to have to look for another license to be able to do that. I would prefer that it come with the simulation toolkit.
