In Houdini you can not only edit the parameters of a surface node, you can reselect the geometry the operation applies to.
Tools on the Polygon tab let you modify polygons in the scene view.
Tools on the Model tab let you edit objects in the scene view.
You can mark a chain of compilable SOPs as a compiled block which can execute much faster in parallel.
Many geometry (SOP) nodes allow you to use them in Python scripts to generate geometry programmatically.
