The verdict
These verified examples are cordless models. Because no manufacturer corded model was established for this comparison, judge the corded-versus-cordless trade-off by power source and yard layout, not by these two tools as direct equivalents.
A large yard with obstacles: EGO POWER+ ST1623T
Battery operation avoids a trailing extension cord; EGO lists a 16-inch cutting swath.
Long sessions near an outlet: DEWALT DCST972B
This DEWALT is cordless too; it does not represent a corded product, so compare a corded alternative by its actual specs before deciding.

Common questions
Questions before you buy
Is cordless or corded better for a string trimmer?
Cordless suits yards where freedom of movement matters and the battery can cover the job. Corded avoids battery changes but needs a safe outlet and cord management.
Does a corded trimmer have unlimited runtime?
It avoids battery runtime limits while plugged in, but reach depends on the cord and outlet. Keep the cord clear of the cutting head and follow the manual.
Are battery trimmers powerful enough for thick weeds?
Some high-voltage cordless models specify wide cutting paths and thicker line. For brush, use a tool and cutting attachment designed for that work.
What does a cordless trimmer cost to run?
That depends on electricity, battery life and use. This comparison omits prices and does not estimate operating costs.
