Nice comparison.... it would be good to know how long the Terragen render took.

The short answer to your question (why the difference in quality) is that Terragen's quality comes at a price of very long render times.

It is possible to get to the samimilar levels of quality in Vue, but then again, at the cost of longer render times.

It is not possible to get the same results in both software simply because the render engines are different.
