We could set up dozens of matrixes and comparative documents that boast about how awesome ExtendSim is and slant the results in our favor since we would be 'authoring the study'. But that's not right as your needs are vastly different than most others. We are happy to give you guidance about how ExtendSim is designed and how it would handle the various challenges you could put it up against. But in the end, you are the best determinant of which tool would best suit your particular needs.
So, ask us questions - any question - and we're happy to tell you how ExtendSim works and compares to other simulation packages.
