It's terrible because it teaches everything in isolation. You have a section for this tag, a section for this function, on and on. You never get a feel for how all the pieces fit together to build something non-trivial. It's only useful as a reference. And even for that purpose its terrible because the information density is way too low.

It's good for a basic reference when you don't want to wade through the W3C spec. It's not good for learning.

I hate the ads, but otherwise the content was good enough for me to go back every so often

The only issue with w3schools is it is basic. Otherwise it covers a lot of material fairly well. At least it's not wrong, like many other resources.

That was not my opinion, it was from the linked thread at the top.
