I voted for Gravity emitters (for the same reason as in the other thread), and for the Colony Ship Bombs. That scenario is probably the hardest I've played so far by a very wide margin due to the power of the colony ships, aside from the first time I tried the Neinzul Mourner Warden scenario and thought "Well, why not just pop all of these all at once? That's a great idea!"
I also agree with TechSY730 that if Special Forces spawn rates were up for a nerf, I would have voted for them, even though it encourages the feeling that the human remnant forces cannot win in a contest of strength. However, if they did get a nerf, they might also need some slight behavior modifications. The first game I played after special forces were changed, I ended up activating the Botnet Golem for the first time and baiting the special forces into a system I invaded with it. I gained a little over a thousand zombies from that, which now kindly kill the special forces as they race to their own doom trying to clear out the roughly 1000 zombies that are still in that system, and every time those zombies start getting thinned out I send the Botnet back to make some more. The special forces don't stand a chance of cleansing the system of the zombies unless I get distracted for a very long time since they keep arriving at the system piecemeal, and this is despite one or two exo waves having passed through that system on the way to my territory.
