First my vote goes to Poser.
But?

A great artist can make GREAT art with a paper and a Pensil.
An artist with no inspiration can do close to nothing with the best tools around.

So? Close your eyes. What is your Goal? And what is your budget?
Read, search the net.
Perhaps you will find that Anime studio is better for you? Or Poser, or DS4?

So the first question you have to ask yourself; What is my goal?
And what is then the best tool to achieve my Goal?

Poser is a fantastic tool, and some artist have been making unbelivable art with it.
But if you start from close to zero,
K N O W before you start, that even with the best idea's it is far from a one click solution
