Nah. Disney+ seems meh. I've seen the classic movies when I was little and later as an adult. I'm not itching to see them again on demand. Star wars sucks. Pixar movies are cool, but not to the point I must watch again. And I've seen all the marvel stuff already. All in all, I'd say Disney can't bring in as many eyes consitently with what content they'll have.
For Netflix, I'm sure most people have least 2 dozen shows or movies in their list they've yet to watch on. I have a huge queue of content to look at. Netflix for all it's political pushing or wtv, is pretty enjoyed by all.
Never heard of HBO Max. And super series shows aren't what people always want. Whichever streaming puts out the best sitcoms will win. The next big bang theory on pne of these streaming things is what they should all be aiming for.
