Pixologic ➔ Maxon ZBrush

I really hope that Nomad Sculpt will get a full-featured desktop version. This would be the perfect time to introduce that. But in the mean time, 3D-Coat is definitely worth checking out, and of course we all still hope that Blender’s Sculpt Mode will get more mature in the next few years.

Then there’s the rising Substance Modeler, but yeah, it’s Adobe and requires a pricy subscription, like ZBrush.
