Comparing BIM usage in Autocad Revit and Archicad

conduct a case study about comparing the two BIM platforms Archicad and Autocad Revit in terms of their user interface, quality of project outcome/workflow, data exchange/file formats, their values in the industry, why is one dominating the other, to what extend do both have an economical/temporal efficiency, and which reasons lead to the decision of using one of these softwares for an architecture office, since both have their pros and cons, different strengths when working with others( e.g. collaboration/operability) as well as different approaches to handling BIM levels; should the decision be based on which one is more enjoyable (emotional decision) or based on which one is already the industry standard/more efficient time and money wise (business decision). I would really like to put both softwares into contrast, compare and analyse them. I also need a questionnaire to be used in this case study, or an interview with someone who can answer specific questions relating to the two BIM platforms Archicad and Autocad Revit. 2000 words are required.
