The Classic 1 is smaller than I really wanted, whereas the Chubby 1 is only slightly bigger. However, the difference in lathering ability right out of the box is quite substantial. Chubby did its thing right away while I had to really work at loading the Classic 1 with soap. I may eventually BST the Classic 1 b/c it is probably a really nice brush for someone that appreciates small brushes. Sorry for the poor photo quality.
