TS has been steadily upgraded by Caligari, so I wouldn't call it outdated. More work on it than Carrara for sure. Carrara is basically the same as when it was called Ray Dream.

Humankind has not woven the web of life. We are but one thread within it.
Whatever we do to the web, we do to ourselves. All things are bound together.
All things connect......Chief Seattle, 1854
