I agree that brown noise generally sounds more calming and pleasant, for example some people enjoy falling asleep to brown noise. In my personal use case of shutting out external noises, I find that it's only the higher frequencies that can make it through the noise cancelling headphones and earplugs, and pink noise helps my brain ignore those better than brown noise, as it melts into the pink noise more closely. It's definitely worth trying both out, in various environments, to figure out what works best for you.
