Well, here is a quick difference between RER and SER

$\square$ In RER 80s ribosomes are present. they are bound by their larger sub-unit with the help of two glycoproteins called as $\bf Ribophorin-I~and~Ribophorin-II$. Ribosomes are absent in SER.

$\square$ RER are more stable structures than SER

$\square$ RER is mainly composed of cisternae and vesicles while SER is mainly composed of tubules.

$\square$ RER is abundantly present in the cells actively involved with `protein synthesis` e.g pancreas, liver etc. SER is abundant in cells concerned with glycogen and lipid metabolism. e.g Adipose tissue, muscles etc.

heres an easy answer: smooth ER doesnt have ribosomes attached. Those Ribosomes are what makes the rough ER rough
