iOS 8 vs Android 5.0 Lollipop Review: Material Difference - Forbes

"Comparing the iOS 8 and Android 5.0 Lollipop is a shock, because for the first time in Android history it has become more design focused than iOS. The ugly duckling is finally a swan. Its design is both visual, instructional and altogether more ambitious.

Not everything is right out of the gate. If anything Material Design is overly white and spread out (you can see less information in most apps – eg fewer emails, lines of text, etc) whereas its predecessor Android 4.4 KitKat was too dark and dense."
