I compared #DataCamp to #DataQuest https://www.dataquest.io/

I felt like DQ's teaching method would be much faster and less prone to "I just did this in the prior course, but I can't recall a bit of it". However, DQ has only ~70 courses (versus 300+ on DataCamp) and won't tell you how much it costs without first creating an account. (Quite a scumbag marketing tactic. I'm supposing it is used to persuade clueless investors that DC's growth is unending.)
