I liked the Brilliance design originally. The bottoms stack well, and you can fit multiple containers within the largest container as an organizer. More efficient than our older Premier containers

However, the lids are the opposite - They really can't be securely stacked on top of each other like all our previous Rubbermaid Premier products. The lids take up more vertical space, as well. 

So, the bottoms can be stored nice and neat on our shelves, while the lids are messy and unstable. 

We held on to one of our old large Premier bottoms to help organize the Brilliance lids from falling all over the place.
