For me the choice was - and is - Poser 7. I do exclusively toonish stills (several renders with different shader trees) that are usually layered in postwork for a "drawn" like effect. I tried D|S twice at different times, but didn't find it suitable for my needs at the time. Material Room's awesome power has been a key deciding factor in my choice. Also Poser 7 is very stable on my system so that also counts big time. I've only had a couple of Poser 7 crashes ever. One doesn't need to rig or animate to prefer Poser over D|S. It's all about the needs. There are just so many ways to use these programs.
