It depends on what you want to create. I work with Bryce 5 and for me its enough. Its an all-in-one package, its easy to work with and can also create very realistic images. Theres also tons of free stuff to download. Feel free to check out my gallery for some examples. Apart from the characters (Poser), its all Bryce.
