While POVRAY has nice features... Really, computer graphics is an ecosystem. And parts that don't really fit that ecosystem are not that helpful in the long run.

Blender's used in actual production, which means lots of tiny things that people doing production work might like to have, have been implemented there.

If one wants to code ones graphics then Blender can serve that need just fine - it has an extensive Python API. Leanrning which will serve one much better than learning the obscure POVRAY script.

Don't guide beginners to POVRAY, please. It will only hurt them in the end. This is just from an ecological perspective.
