For Grineer and Corpus, I generally go with Radiation+Toxin. For the Grineer, this gives you a bonus against both armor types (though the bonus against ferrite is relatively small). For the Corpus, this gives you damage through the shield that deals bonus damage to the living units (although decreased damage to robotic), and the radiation deals bonus damage to robotics (at the cost of dealing slightly less damage to the normal shields used by the squishier units). You also get a chance for the fantastic Radiation proc on the enemies that you don't instantly kill.
