Well, that is my experience too. My background is game programming school, after first learbing flash, second trimester was about making a game using html/css/js (no pixijs or phaser here). I did find MDN hard to read and preferred W3School. Today however I tend to prefer MDN. MDN is richer, more exact, more complete. But being minimal is better when you already unfamiliar with basics. TLDR : MDN pair well with W3School, imo both are fine as they are.
