best thing is to mix it up really!!! somedays poser is best, another day vue is best and so on, as you have three programs, use three programs, learn a bit about each, try the same scene in all programs and see which one you like best, that will give you an idea of which program you are gonna render in, when you plan future similar scenes, i find poser best for showing skin and hair textures off to their best, but when i want a detailed scene, with accurate and specific lighting i use Vue5 infinate!!! different projects require different apps basically.
