" Clutter uses OpenGL (and optionally OpenGL ES) for rendering but with an
API which hides the underlying GL complexity from the developer"

Take a look a their API documentation (http://clutter-project.org/docs/) ...
this is an abstraction. Clutter is designed for something completely
different.
It feels like " OpenSceneGraph".

What GtkGLExt provides is a way to still work with your GTK knowledge an do
some OpenGL stuff.

As always it depends on what are you trying to achieve.
