This can be somewhat of a controversial subject! There is an argument that sending a solid tine into the ground is not actually aerating the soil, as the times can compact the soil as they press into the ground. But what they are effective for (In my humble opinion) is reliving the surface tension of the soil and creating a void that can effectively collapse in on itself creating cracks and reliving some surface compaction.
It is also a great option - as in this instance, where creating plug holes would not have fit in with the available time, and the scheduled use of this surface for an upcoming wedding.
