"Bentley Architecture" Vs "Revit" . . . . who will win the Global race

The AutoCAD AEC days of the mid 90’s were probably my first foray into Parametric 3D modelling. But as a design tool I found it very stiff and inflexible.  Lots of products have since come and gone. There was a pretty good one called Reflex (not sure what company or if it still exists) but it seems to have died a natural death not having the resources of Autodesk or Bentley. Vector works also seems to be a pretty good product. Being a diehard Microstation user however I am currently
using Bentley architecture. In general I believe there will be a remarkable growth factor in BIM technology and integrated practice over the next few years, probably a growth rate of 8% per year.  In fact I think it will become increasingly difficult to find work if one is not trained on one BIM software package or the other.

 In the Uk Market Revit seems to have gained the upper hand over Bentley Architecture. A probable reason for this is that Microstation products generally tend to be used for larger multidisciplinary projects and less so on smaller schemes whereas Autodesk products seem to be more commonly used by smaller practices and is not
so commonly used on large infrastructural projects

 I would say currentlyonly 7% of the construction industry in the UK uses BIM and of that,  90% of available employment opportunity is Revit based. I have not used it personally but I assume that it is as good as Bentley Architecture. I suspect however that Bentleys Global reach and resources will allow it to keep going and be an equal contender for market dominance though maybe not as popular.
