Aspect of the Cheetah and Aspect of the Pack are a base +30% to movement speed, modifiable by talent in the Beast Mastery tree.
Druid travel form is +40% to movement speed outdoors, which makes it faster than the speed boost feral talent will give a druid in cat form outdoors (+30%).
Hunters have an obvious advantage here: Aspect of the Cheetah and Aspect of the Pack function indoors. What better way to return to where you last wiped in an instance than for your hunter to turn on Aspect of the Pack?
