Is aerating or dethatching better?

While dethatching removes the layer of thatch above the soil surface, aeration removes actual plugs of soil from your yard. With looser, more nutrient-rich soil, root systems can spread out and grow deeper into the soil. Holes in your yard may not be glamorous, but they'll quickly fill in with dense, healthy grass.
