Why is MathML better than other solutions?

Overview of native MathML support: advantage and status
  • W3C recommendation and web-platform-tests coverage for the best interoperability.
  • Native implementation for efficient layout and automatic reflow.
  • No external resources required except for purely stylistic information.
  • Cross-compatible and high-quality rendering possible using TeX and OpenType MATH rules.
  • Visual rendering fully controlled by font and CSS styling.
  • Compatible with the other HTML5 technologies for best user and developer experience.
  • Formula content works well with browser UI: zooming, select, copy & paste, find text, etc.
  • Information properly exposed to assistive technologies.
