Ok, the review quoted below may be biased, but the Solibri product is worth keeping in mind. They also make a free IFC Optimizer that can be useful when moving a model from ArchiCAD into Revit.
Navisworks is now an Autodesk product, with a vast sales and marketing machinery to boost its implementation, so this is understandable. But Solibri Model Checker does so much more than Navisworks, and while it has its share of success stories, especially in Europe where Solibri is based, it does not enjoy the perception of near-ubiquitous adoption that an application like Navisworks has, at least in the US. Solibri Model Checker is gaining some momentum in FIATECH and the GSA, which is promising.

Solibri Model Checker v7: AECbytes Product Review

| Image from AECbytes review page |
Solibri Model Checker (SMC) is an immensely valuable tool, but it's purpose in our toolbox @ my firm is distinctly different than Navisworks.
Navis is our building coordination tool. SMC is a kick-butt model checker/comparison/QTO tool that's saved us large amounts of time and money.
Both are hugely important to our VDC process, but in Venn diagram terms, there is very little overlap.
