Have you noticed there are several bows with different names? For example a Flatbow. Well, these bows are unique in their different ways, I'll explain why.

-Short Bow: Has a Short Range and high accuracy, it works good with a Sundering Bowstring.

-Hornbow: These have decent accuracy and range, it's good to use them for conditions since the accuracy is pretty good.

-Long Bow: Long Bows has the longest range in game but the lowest accuracy at the same time, these bows are usually used for pulling small groups of enemies. They would work pretty well with Elementals Bowstrings. (Like Pulling with Barrage Ice Elementals with a Fiery Bowstring, you don't only pull but you add decent damage at the same time!)

There are a couple of more bows, but those are very similars to the bows I've just listed, like a Half Moon(Short Bow) or a Flat Bow (Long Bow).
