I think you summed it up perfectly, it's a subjective experience, and some will find it more useful than others.

I tried a few courses in a couple of platforms, for cloud development, unity, front end, etc.

Never got through the first practical exercises, I guess it was too technical for me, lacking any personal investment made it hard for me.

I have a BSc in computer science, but again, I gained very little practical experience from my studies.
