Butterfly valves are smaller.
Butterfly valves indicate valve position by handle position. gate valves (with the exception of OS&Y) dcn't.

However, the disc of the Butterfly will be in the flow path. They could erode depending on the material passing through them. And, for the high end valves, they can be more expensive first cost.

gates are good for throttling duty in my opinion, but definitely not for positive shut-off.
I am more partial to full port ball valves for shut-off, even globe valves on by-pass applications.
