Vue has ecosystems which makes a massive difference for creating landscape vegetation. And you can actually get away with throwing a quick ecosystem together and having it look Ok.

If you want to see which is better for what you need then probably the best thing is to look through the Poser and Vue Galleries and see which most suits the style you're aiming for. MassiSan does a lot of jungle/woodland type landscapes in Vue. (Actually looking at that Gallery tends to depress me a bit! LOL!)
