I really dislike video courses. There is, usually, no good way to quickly scan for the important parts.

If there is stuff you already know, skipping forward minutes will keep you wondering whether you have missed something important. With text you can scan through unimportant parts relatively easy, while knowing you didn't miss something important.

Mega tutorials are a very poor format because they don't cover each topic in a self-contained manner, nor they provide a minimum working example to test.

However, they are way better than any video course.

I guess it depends on the type of person you are and how you learn best. In my case for example, I learn better by coding while following a video than when I have read through a massive blog post (Which involves a lot of copying and pasting). That said, text format is great in book form because you can easily reference a concept without having to scroll through an endless page. The only downside with books is you have to wait longer for the content to be updated. Just my 2 cents.
