There are really too many factors involved to give you a good answer. Steppers may not need to be geared at all. And gearing steppers can be detrimental to high speed performance. Gearing a servo depends on the particular servo to an extent. Different servos have different top speeds. You generally want to gear according to that. How fast you want the machine to move also needs to be considered.
