There is one more very large difference. Your onboard pneumatics system (with its compressor and pressure switch and everything else) gets checked by the inspectors for proper operation. Your proposed setup does not. Its design might well be equivalent, but the execution does not get evaluated by people responsible for ensuring that every team plays by the rules.

(The more fundamental difference is that your proposed setup won't work. The Spike control input is a 5 volt signal.)
