Bizagi Studio is definitely playing in a higher league than the rest of its competitors that I'm aware - some of them with very big software companies behind. It provides the same or better functionality with a very sensible and reliable development tool that is much simple to use than any other.
Excellent data management, excellent data navigation and excellent integration tools. Close to be a software masterpiece.
Fantastic business strategy by being an open access development tool and having simple and open pricing of the Automation Engine.
