Probably because people tend to think in extremes and "1984" shows the ultimate dystopian world set around totalitarian regime, mass invigilation with no place for individuality. "Brave New World" is indeed much closer to our real world but honestly, I think our reality seems to be heading in a direction where we'll see more of both novels in it. I recommend reading both and Eugene Zamiatin's "We" novel which most likely inspired both Orwell and Huxley: https://en.wikipedia.org/wiki/We_(novel)?useskin=vector https://en.wikipedia.org/wiki/We_(novel)?useskin=vector
