Well, neither really. An appropriately chosen motor for the battery voltage you have, geared for the speed you want (within reason) is the best bet.
If you wayy underrev and overgear (to compensate) a BL motor, you have more chance for cogging since there are less back EMF pulses for the ESC to read. Not to mention your burst current will be higher because of the higher load.
If you spin a motor too fast, you start getting heat for no reason even though it isn't loaded as much with short gearing.
