Favourite factions to fight?

Favourite: Automatons (mainly because shooting down their drop ships with 1 SPEAR rocket is funny).

Least: Terminids (find being swarmed annoying, some of my favourite enemy designs though. - maybe them being a more melee focused faction and constantly having to move is my issue.)

Natural: Illuminate (can be annoying but I also like the enemy designs, also like shooting down leviathans.)
