No browser is perfect, this is an unfortunate situation we must live with. But ranking my experience developing responsive hybrid applications, Safari gets an A- and Mobile Safari a B+, while Mobile Chrome get's a D on a good day. Overall my rankings currently look something like this:

Safari: A-
Edge: A- (tentative, I haven't worked with it often enough yet to honestly rank it)
Mobile Safari: B+
Firefox: B+
IE11: B+
Opera: B
IE10: B
Chrome: B- (on a good day when I'm happy with how nice their dev tools are)
IE8/9: C-
Mobile Chrome: D (on days I'm not cursing them)
