[Marvel] What is the difference between the Phoenix Force and Galactus in terms of their roles as cosmic entities ?

Aren’t they both destroyers? It seems kind of redundant considering their respective power levels? Would love to hear your thoughts.

They've actually talked about this with each other. 

The Phoenix creates life but burns up stars, so that the lifespan of the universe ultimately winds down; Galactus destroys planets but it will ultimately be used to start a new universe. 

It's the difference between someone who gives you something at a cost to be paid later, and someone who takes from you now with the promise of paying you back in full later on.
