- From my experience em is very useful, when you want do specify size based on parent font-size, eg. icons, buttons, spinners
- You can make using rem easier by Sass functions (https://css-tricks.com/snippets/sass/px-to-em-functions/), or by setting body font-size to 62.5% (https://developer.mozilla.org/en/docs/Web/CSS/font-size#Rems). In second approach when you want to have eg. 15px, you can set it as 1.5rem.
