If you want to do ACTUAL 3D rendering your choises are OpenGL and OpenGL,
Clutter doesn't come anywhere near it.
It's true that the API is getting better in 3.0+ but you can still do
the same with 2.0+.
Also it's a matter of personal taste.
At the dawn of time John Carmack chose OpenGL and urged all GPU
vendors to make OpenGL drivers
because of the horrible DirectX API.
Of course DirectX has come a long way since, but if you want any form
of cross-platform support
your only choice is still OpenGL.

It may be niche as in not many apps use it, but that hardly makes it
any less important.
When companies like Autodesk ports ther many many $$$ apps
to Linux they don't have the choice of using GTK+
As far  as I can tell GTK+ is the only widget API on any PC platform
that doesn't have an OpenGL widget/view.
Not being able to use advanced 3D visualizations in modern day apps
seems rather odd IMNSHO.
