Well... it depends.

I primarily use D|S because it's a lot lighter on resources (esp. on the laptop), and because renders usually happen a whole lot faster under the same conditions (in Firefly vs. 3Delight, anyway).

Poser does have a much easier-to-use AOL setup, which makes it handy for those particular tasks, but it's offset by the slower interface/dial reaction, esp. when I start loading a lot of high-poly figures up into a scene.

OTOH, I'm kinda biased... I have a lot of professional attachments to D|S.

IMHO, try it out anyway - the most it will cost you is disk space.
