It depends ofc, I guess my problems/questios aren't the same as yours. For example I wouldn't look up about powershell modules on youtube, I would go to Microsofts docs. Same with windows error codes. And Linux problems would be the arch Wikipedia. And game wikis are great source for games. But this is all factual info. Maybe you are thinking of something else.

For reviews: I look through multiple articles both comparisons and about that product alone, multiple YouTube videos (mostly to get a feel for it and more info to search for), I always look at the specs and compare it with similar products. I also look up the brand if I haven't heard of them. But it depends on the product, games are mostly only YouTube, a few gameplay videos is enough if it isn't a game like cyberpunk that was broken at launch.

My experience with reddit users are often that they are just saying the same thing as everyone else because they believe that is correct not because they know. That isn't helpful to me. Especially not if they are just saying what is the best in the world not best for the person asking. I was on some niched subs and that happened all the time. So I rather find info from someone who cares about their reputation and tries to give accurate info or a friend/coworker I trust. But again I never used reddit in that way so I could have missed a lot of great guides and useful info.

I think reddit was great for subjective matters to gain different perspectives. So subjects that is not factual do I think reddit can be a great at. That is why I was confused why so many seems to use reddit for finding answers.

It sounds like it is for very specific problems and feelings and experience for a company/product. Did I get that right?
