What are the key differences between a digestive biscuit and a graham cracker in terms of taste, texture, and ingredients?

Digestive biscuits are slightly sweet, wheat-based cookies with a crumbly texture and a hint of malt flavor. Graham crackers are sweeter, made with graham flour, and have a more pronounced honey taste. Graham crackers are also crispier and have a coarser texture compared to digestive biscuits.
