Well,
- the learning curve of ArchiCAD is twice faster than Revit
- ArchiCAD interface is easier to understand
- ArchiCAD library is far more useful as it provides really useful elements
- It's easier to achieve graphically well-done 2D drawings with ArchiCAD
- Layouts are easier to make and to manage with ArchiCAD
- Some tools are really much more powerful like the magic wand and the dimension editing. Also, it's easier to work and edit the model in 3D with ArchiCAD than Revit
- Complex profiles in ArchiCAD are much more powerful than the equivalent (if any) in Revit
- Exporting and importing IFC are easier and more powerful in ArchiCAD
- ...
I surely forget some but there's a lot more functions in ArchiCAD that are better than Revit.
