In what way?

The use of actuators vs pneumatics is always a careful deliberation.

In terms of simplicity, actuators would be better.

However in terms of speed, weight, and oddly enough durability the pneumatic ram would be in an advantage.

Both methods are not wrong. In fact the most famous true walker I know, Mechadon, uses actuators. However in this application I would prefer to use co2 because of speed and weight.
