that is weird, BTT's space switching should really be instant when used via keyboard shortcuts. (Developer of BTT here)
One advantage of BTT's current implementation is that it still allows you to move windows to the next/previous space while dragging them and simultaneously executing the "Move Left / Right a space" action. In that case there will be an animation but it will at least work.
