 picturePolyfill is better than picturefill because:
 
-* it's **15x faster** on IE 10, **8x faster** on mobile Safari, **6x faster** on Firefox and Safari, **4x faster** on Chrome and Opera [see performance test](http://jsperf.com/picturepolyfill-204-vs-picturefill-121-performance-test)
 * it uses the **real `picture` markup**
+* it's **15x faster** on IE 10, **8x faster** on mobile Safari, **6x faster** on Firefox and Safari, **4x faster** on Chrome and Opera [see performance test](http://jsperf.com/picturepolyfill-300-vs-picturefill-121-performance-test/2)
+* it **better handles AJAX calls** because it lets you parse only a section of your DOM, passing the parent element to the `parse` method
 * it gives you the ability to **choose a default image** that you want to show on Internet Explorer desktop, without the need to add any comment
-* it's **solid**, since `picturePolyfill` code is test driven with full code coverage
+* it's **solid**, since its code is all covered by tests
