The fact that Nemetschek (the developer of AllPlan) has bought Graphisoft (the developer of ArchiCAD) does not mean that these two are not still competing products, being constantly developed. It is normal that one company offers several solutions in the same field, especially in this global consolidating business environment: Nemetschek offers AllPlan, ArchiCAD and Vectorworks. Autodesk offers AutoCAD Light, AutoCAD, Architectural Desktop (I don't know if it is still called that) and Revit Architecture.
So one should investigate all options and pick the one serving his purposes best.
