Do you prefer Ribbed or Nubby?

How do you guys feel about texture. Who prefers nubby versus ribbed or maybe other raised textures. I think for clitoral stimulation, nice soft wiggly nubs would be nice. I think for vaginal stimulation, raised textures like veins or ribs might work but it seems like it really needs lubrication if you are going to insert something with texture, as it could hurt if not slick enough. Thoughts anyone
