I've had good luck in the middle. I run my differentials directly off of an
8t gear mounted on the motor, and then run large wheels directly off of the
output.
When playing around with designs (I spent quite a while looking at different
designs) I found that the most important thing in getting high efficiency
was to minimize the gear count in forward motion, and to try and minimize
the use of 8t gears.
In your design I would start by driving the lower differential using a 8t
gear, and running tires off of the two protruding axles. This way for
forward motion you only have one gear mesh in motion between the motor and
your wheels.
