I definitely find `box-sizing: border-box` fits my mental model much better. I rarely find a need to think about `positioning` though and I think the article doesn't give enough credit for `display: flex` and `display: grid`. I tend to reach for `display: flex` as a default and find it much more intuitive. Whether it's easier for a beginner is a different question though.
