Jimmy Gunawan compares Maya's SOuP BMesh against Blender's Skin Modifier.
As you knew already Maya recently got BMesh via SOuP plugins allowing us to do quick meshing based on Joint similar to ZSphere inside ZBrush.. While on the other side, Blender Open Source 3D is soon to be upgraded to version
2.542.64 and officially gets the awesome Skin Modifier from Nicholas Bishop (!)
NOTE: ZSpheres as the original of this method of meshing is still cool. But for me, I actually prefer having it inside Blender or Maya.
To test the power of both BMesh and Skin Modifier, I made this funny character (Sadako aka Samara from The Ring) earlier today, just less than an hour of work inside Blender.
Both SOuP BMesh and Blender Skin Modifier handle the creation of Mesh really quite well. Although I must say that Blender Skin Modifier has few more tricks and options that make it the winner. I would do more modeling inside Blender this way, ala ZSpheres.
Although I may have to say that SOuP BMesh also has its advantages being inside Maya because it is a node based system and really can be used for all kind of procedural effects. SOuP BMesh is fairly new and I bet it can be made even better.
I think to improve SOuP BMesh, it needs the "Loose" and Smooth.
On the other hand, Blender Skin Modifier has been in development for a while, it was quite fast development and consistent. The fact that Skin Modifier is now available for anyone inside Blender Open Source 3D software is just brilliant.
