A properly strategic tool that we used to model (and change) a large organisation's structure - with clear visualisations that work for Board and Exco discussions. I have used it extensively - and it's proven highly versatile for business planning, organisational change, and insight into inefficient deployments of managers.

No substantial downsides. Useful that it can import staffing and position data and deal with them separately, allowing for modelling of different types of organisational change. Review collected by and hosted on G2.com.
