What's the difference between a Leuchtturm1917 and a cheaper dotted journal?

The Leuchtturm1917 Official Bullet Journal Edition includes BuJo-specific features like numbered pages, an index, and a pocket guide, plus 120gsm paper. Budget alternatives often match the page count and dot grid for far less but vary more in paper quality and binding. Choose based on whether you want the official BuJo structure or just a serviceable dot grid.
