I find it very easy to use, but I've been using such programs for years :)

You should try Vue, Bryce and Carrara demos, see what you like as it's always a deeply perosnal choice.

For me, Vue hands down. Unlike the "high end pro apps", you don't have a ridiculous "nested menus from hell" interface it's far more "what you see is what you get", Bryce was the first to use that kind of idealogy of interface, then Poser and Vue picked it up.

See some of the tutorials on my site, link is in my signature, or the GeekAtPlay.com ones, to see how things go with Vue, I find it pretty logical without being "abstract to hell" :)

Vue's a lot more than just backgrounds, in the sense you make scenes, not merely backdrops, though you can of course make backdrops.
Have a look at my gallery :)
