For the most recent ArtStation Challenge, I decided to use Gabriel Alsteen's concept for the Holy Grail. For this model, I created the mesh in Maya, sculpted detail in ZBrush, created the textures using Maya's Hypershade and rendered it using Arnold. I also used tileable textures to create displacement maps for some of the more complex details.
