Nether quartz vs certus. Only mentioning for now.
I'd second that the border on the chiseled and pillar variations should probably be less pronounced to make them look better when stacked. The block version matches the Quartz Block. What's being compared in the image is Vanilla's "Smooth Quartz Block", while our block matches Vanilla's "Block of Quartz". - Gimpansor
I was actually inquiring about the pillar and chiseld block as the minecraft variants do not have a hard border between them. Having a transition between each block isn't actually bad. Myabe it should just be a smoother or more detailed. Also another idea would be to allow pillars to face any direction and not just align them with an axis. So players could make different pattern depending on the rotation. But that might better fit into a different block. Something like a capstone(?) for a pillar. Like a transition block between a pillar and a chiseled block.
