It's good for Commando because you can make it safe if blocked, but for Cyber and Cutthroat, D3 and D4 are probably better.
D4 is +18 on hit, -7 on block, so you could use it to set up 50/50s in Cutthroat whilst being relatively safe if blocked. D1 will give you +25 on hit and you have to be closer to make it connect, giving you a better chance for his close range overhead and low to hit. It is -9, so using it depends on your opponent. If they react slowly to pokes and are bad at punishing, you can probably use it.
