I've read Brave New World (while listening to Iron Maiden's Brave New World) but that was a while ago, my memory of it might be a little thin.
From what I recollect though, the antagonist governments reached the same conclusion, just devised different methods of enforcing that conclusion. The conclusion being "Stability is more important than individual happiness."; Brave New World kept people perpetually doped up and indoctrinated into a society starved of any real hardship, thus keeping the populace emotionally infantile and unable to even imagine that their lives are that bad or need improving. 1984 kept people constantly paranoid and fearful, and starved them of friendship, family, free time, education, even the concepts of objective truth or facts, absolutely anything that might upset the enforced social hierarchy or allow any mobility at all; the ruling class believed in power, power for the sake of power, because the pursuit and maintenance of power was, to them, the end-all be-all goal as the most stable social equilibrium.
The two books even have a similar arc in the main character getting to meet natural, untainted people and getting to compare their own miserable existence against their freer, more substantive and meaningful existences.
