Personally, I would always chose a more developed software package before a brand new one. Poser 5 may or may not have a few bugs, but I have never seen a first-release software package that did not have TONS of bugs - like the early releases of Poser 5!

Also, if you post a newbie Poser question here on Renderosity, you can count on about a million very insightful replies...it will take a while for DAZ to reach that point.
