Differences between Dynamo for Revit and Grasshoper for Rhino

Question

if there are experts users of both plug-ins, could someone please elaborate on the differences in the functionalities? Are there design tasks which can be solved/performed with the one but not with the other? I am not an expert user of any of them, and have worked only with Dynamo so far. I am aware that both are algorithmic modelling tools, but also that much more than geometrical data can be accessed and modelled (with Dynamo this is definitely the case). So I was wondering: are there areas/tasks which can be covered and solved with the one but not with the other, and are there some significant differences in the scope and depth of the tasks which can be achieved with the one but not with the other?
