Fructose is sweeter to the palate so one can actually use less of it than sucrose (table or cane sugar). Its why honey is so sweet, the majority of which is fructose.

I like fructose, but not dumped in the quantities they do in soft drinks. And I like fructose from bees, not corn. But alas, fructose from bees is more expensive than fructose from corn.

I can elaborate on the sweet carbohydrates if anyone insists... ok maybe not.
