I read both of them in middle school. The 7th grade math teacher had a bookshelf in her classroom. I have no idea why, but 'Brave New World' was one of the books. I checked 1984 out of the library after reading that one.
Honestly, I don't know exactly what either of them has to do with a 'corporatocracy'. Brave New World was about a society that deliberately dumbed people down(before birth, even) and gave people meaningless entertainment ('bumblepuppy') and drugs ('soma'), and others('everyone belongs to everyone else'), to keep them placated and docile.
Anyone who doesn't agree with this 'society'(i.e people who we would consider normal) are called 'savages' and live on reservations.
1984 takes place in a police state, which encourages everyone to 'love' Big Brother above all else(even parents, who children are encouraged to snitch on if they show any disloyalty to the Party.(much like the USSR.))
They also 'hate' their enemies, (Two Minutes Hate), and have 'always been at war with Eastasia', which is just a system to keep the populace in check. (As soon as they make peace with Eastasia, they go to war with Eurasia, and so on.)
The Party also keeps the populace dumbed down and docile, but by different means(the cinema &etc.) They also have four Ministries which are the exact opposite of what they say they are, most notably the Ministry of 'Truth', which is in charge of censorship and producing
Pro-Big Brother materials.
I really don't see what a 'corporatocracy' has to do with it. Both societies decidedly do not have an emphasis on monetary systems(in 1984, the best things(nice houses, cars, good rations) go to the people in the Inner Party, but money(as far as I can remember) is not mentioned. In Brave New World they have constant production(they throw things away as soon as they get worn out) so money isn't really an issue(or that the book focuses on.)
Neither of the books mentions anything at all to do with 'corporations' as we know them.
In my opinion, we're currently living elements of both books. The dumbing down and emphasis on shallow materialism(at the expense of true meaning(human connections and belief/ spirituality(whatever you want to call it) from Brave New World, and the false narratives being shoved at us from all directions(Ministry of 'Truth'), mainly from the MSM.
