What is the real functional difference between "Geometrical Set" and "Ordered Geometrical Set" in Catia V5?

Ordered geometrical Set: it depends what you do first, second,... like in an BODY. It makes a difference if you first Filet, then Draft (or Shell) or the other way round (First Draft then Fillet)
Geometrical Set : more like a Windows Folder. It is for structuring your Modell.
If you are working in Hybrid Design (mixing surface and solids in the Same structure you can should use OGS.
Dassault prefers using Ordered Sets
If you are working for Audi, BMW, Mercedes, VW it is FORBIDDEN to use Ordered geometrical Sets. Hybrid Design is also FORBIDDEN.

Greetings

People who wants to use Ordered Geometrical Set or Hybrid Design should have a clear view of what they really want to do because after it could be a big mess.
You get better organisation with Geometrical sets, because you can create one for your skeleton and then one for the creation of each surfaces you need. it gives a more comprehensive design for the one who look after your design.

I think very good explanation is here:
