Stepping motors are great, except for one
thing. You need more wires to connect to
the motor (at least 4 and sometimes 6).
And in the 4 wire case, I don't believe
any can be ground. With a DC motor, you
need 2 wires, which is really no wires if
you use the center conductor and shield of
the coax.
In a remote application, running an extra
control cable just to use a stepper may
not be worth the effort.
In non remote applications, I think steppers
are the only way to go.
