Peaceful is the only good happiness type for stock SE4. Neutral is just absurd. Bloodthirsty has way too many penalties for colonizing planets and other such early game pre-troop activities.

It is fairly easy to maintain jubilance on your planets once you get troops, if you build enough of them. How many troops do you have per planet? I have found that 120 police troops (small troops with only a cockpit, or armed if you want to spend a lot more resources) will do the trick. Losing a planet gives an increase in anger of 50. 120 police troops have anger decrease of -240 (-2 each). You can lose 4 planets and 40 ships (or 3 planets and 90 ships, or up to 240 ships) in a turn and not notice anything at all, since the 120 troops will cancel out all of the anger increase from the losses.

Urban Pacification Center IIIs decrease anger by -30 per turn, so just 15 troops already match up to the affect of the best UPC...
