Is there a difference between using a dict literal and a dict constructor?
...
I think you have pointed out the most obvious difference. Apart from that,
the first doesn't need to lookup dict which should make it a tiny bit faster

Heap vs Binary Search Tree (BST)
... new elements are almost certain to go at the bottom
heap insertion starts from the bottom, BST must start from the top
