Carrara (especially the Pro version) is a complete 3D app: modeling, texturing, composing and rendering. DAZ looks like it is developing it significantly and it could become a major competitor in the low-cost arena in the future. In this respect, it does compare with big boys like trueSpace and not with specialized applications like Vue or Terragen.
I tried the open Beta and found it still behind Vue and Terragen w.r.t. to rendering, behind Hexagon w.r.t. modeling and behind Studio w.r.t. posing ease, but things could change in the future (in other words, if DAZ decides to make it really their flagship application).
Currently, DAZ worst problem is that they have several applications with significant functionality overlaps and they do not seem to have made up their mind to what to do, i.e. whether to have a few swiss army knives programs or many specialized programs.
