What is the most defining drawback of DC motors in general?

The biggest drawback in any DC motor is the use of the commutator and brush arrangement and the relative motion between them. As a result of this arrangement, they:
  •  Require additional maintenance.
  •  Have a shorter life span.
  •  Possess a higher chance of sparking at the commutator and brush assembly.
