I like to use Terragen, but it's very limited which is why I always come back to Vue. Can't add trees or rocks, or objects - you apparently will with TG2, but I don't know how it'll be implimented. For now I have to do all objects in PS - which come to find out drives many in the TG community crazy. It seems that many specifically want the TG "look" of the render and feel it is marred by postwork. Their (TG that is) goal was to figure out how to make the qualities of light for an outdoor environment as realistic as possible. However - I disagree with the quality of TG clouds when you try to make them thick (3D vertical thickness). That's when it tends to be "very unforgiving" - an excellent description from someone in one of the TG threads. My main problem with Vue is that ALL their materials start with an opacity of %40 - this drives me nuts! In the real world NOTHING has an opacity of %40 - so it makes straight renders look "cartoonish" and unrealistic. When making an ecosystem with plants (and rocks, frankly) I'm unable to lower the opacity and have to make more adjustments in PS - BTW, if anybody knows how to bypass this I'd LOVE to hear it!
