Well this is quite a sensitive matter because i think users will defend their software of choice. In this matter, Maya users will always say their software is the best in the world, and because there are a lot of Maya users their numbers make a difference.
Personally i prefer to give credit to the artist instead a piece of software. A strong modeller will always be good in almost any kind of software just because the user's experience is the best tool.
Regarding that list i would put Modo and Blender ahead of maya and even houdini. Zbrush is more a sculpting software so i wouldn't compare with others besides mudbox or 3dcoat.
