When to use on-click or on-tap w/ Polymer?

I've researched a lot but still haven't found a good answer. When should I use on-click and when on-tap, specifically w/ Polymer?

This guide focuses on programmatic event listeners, so isn't helpful in that regard:

Solution

  • Use on-tap all the time, because the semantics of on-tap are better aligned with mobile devices than on-click.

    For example, on-click does not fire if another finger is touching the screen, or if the element directly under the finger does not have a mouse handler. There are also some complications with getting on-click to work while you are scrolling. Use on-tap unless there is a compelling reason not to.
