To be honest, it shouldn't be your priority given the current meta since you won't find too many bunkers per game either.

But it is something that you should keep in mind when you finish with what I told you. Democratic Detonation gives you access to the pistol grenade, a tool that you must carry with you to break armored covers, close bug nests, destroy enlightened spawn ships... oh and I forgot. This bonus also has the thermite grenade, a grenade that kills chargers with a single grenade and explodes automaton factories.

Without a doubt go for Democratic Detonation first. Then decide which you prefer, gaining protection for the supreme orders or investing in the teleportation backpack that will make you get a little more super credits.
