It might not be faster when the hoverboard is going full speed, but it takes a while for hoverboard to get that fast, and if you hit any walls then the hoverboard comes to a stop and even bounces backwards. Plus the fact that hoverboard can't go diagonal makes it a lot slower for reaching places that aren't straight away. Then things like not being able to go up ladders or cross those small moving bridges on hoverboard makes broom much easier. But I guess they are more expensive.
