I use the Classic editor in combination with AdvancedOasisUI to make Source open first by default. I rarely use the visual tab, but it's sometimes useful as Yatalu mentioned below. As mentioned in the article, Source rarely messes up a page's format and is great to use to fix formatting problems cause by people using the visual editors, mainly the new one. One thing I do like about the new Visual editor is that "VisualEditor" is added to any contributions done with it so it's easy to see if the user or the editor is really the problem with formatting errors (commonly so in my experience) and act accordingly. Classic is what I would recommend to frequent, less hardcore users for these reasons.
