The gear reduction motor runs at a more efficient higher RPM needed for the series-parallel wound motor to run more efficiently.
With better efficiency you do get something for free.
To say the gear reduction starter reduces amps is an understatement. It almost cuts the amp draw in half and cranking time is increased by a barely noticeable amount if at all.
