I wonder if Ionic Framework did remove the click-delay of +/- 300 ms for browser apps / sites. I tested a demo of the framework a while ago and the app just felt slow (perhaps because of the animation or what i thought was the delay on click).

Googled: According to info, they did remove it, but you shouldn't use the ng-touch or fastclick side by side with it (source: http://stackoverflow.com/questions/25419109/ionic-tap-delay-... )
