Amazon Ember vs Helvetica

Two corporate-grade sans-serifs from very different eras. Amazon Ember is a humanist sans drawn by Dalton Maag for Amazon in 2015, tuned for Kindle screens and later rolled out across Amazon.com, Echo, and Fire TV; Helvetica is the 1957 neo-grotesque by Max Miedinger and Eduard Hoffmann that became the default voice of corporate identity worldwide.
