What is the difference between a core aerator and a spike aerator?

A hollow-tine core aerator (also called a plug aerator) extracts finger-sized cylinders of soil and deposits them on top of the lawn, creating open channels that let compacted soil expand, breathe, and absorb water. A solid-spike aerator (or aerator shoes) merely pokes holes by pushing soil sideways and downward, which can actually tighten compacted clay around each hole.
