Compare geometry

Hi,

I am quite new to grasshopper and I am interested in how to best check and get from a list of geometries, 100 no.solids let's say, which ones are the same and which are different.
I could achieve this by evaluating each geometry and get no. of vertices, no. edges, no. of faces, total area of faces , volume, etc... and group by the resulting function ( a resultant of all these parameters/identifier) .
I could also grab the solids and place them on a Line , having as insertion point the Centroid, get all vertices locations( after grouping by the no. Of vertices) and see if there are any similar values which would mean that the geometry is the same.

How would you guys do this .

Thank you.

John.
