Here's my observation.
People at stackoverflow are desperate to close any new question they don't want to answer or have made cascading policies to close down.
People at stackoverflow are edgy and often come out as downright rude. They won't even hesitate with personal attacks behind the correction they make in comments. You can google for random problems and may find solution in there but in comments you get to see lot of people who answer are either voted down or ridiculed.
You are going to learn more from youtube than stackoverflow QA threads.
Duplicate questions often don't have answer to tangent outcomes. For example let's assume I want to learn how to work with node on centos. Another person asks questions on node setup with docker centos setup. Both of our questions have chance of lockdown and both may not get answered. Bad question closing policies.
Lot of people at stackoverflow bleed the elite and edgy in their opinion. You can notice their answers are less factual and more of an attempt of building left liberal progressive utopia. (refer to stackexchange sites if you want to see what I mean)
Stackoverflow has no more friendly vibe. You got to be a female to survive there or have found rare question to not get attacked and closed. I don't see any other scenario through which anyone get treated fairly.
That's my blunt opinion about stackoverflow.
