Hello, I'm starting with 3d modeling and I have no idea which studio would be usefull for me

Which 3D Studio is best for 3D modeling and animations ? It does not matter about difficulty but about quality and real impression.

For survey, can any a bit skilled 3d designer or animator write what is good program for advanced modeling (e.g. movies or professional presentation), how long takes to make some model (e.g. car from gallery and simillar one)

Thanks much for any tips, Eric Falken
