Here's another view: https://html5test.com/compare/browser/chrome-44/ie-Edge/ie-11/safari-9.0/safari-8.0.html https://html5test.com/compare/browser/chrome-44/ie-Edge/ie-1... Safari 8 to Safari 9 got +4 points on HTML5test - only adding some canvas2d features and some CSS selectors. IE11 to Edge got +66 points, adding loads of features. MS also have a clear roadmap, and Apple has very little. I think this is contributing to the sense that Safari is being left behind.
