Material design is a disaster for usability. Android became a bloated, spaced out mess, where you'd fit three menu items on a six inch screen. Information density on the desktop is a joke too.

You can genuinely see more content on an old 3.5 inch iPhone screen than on a 5.2 inch Android screen. Open the Settings app, for example.

Then there's the FAB buttons that go over the top of content, and right where your thumb wants to scroll.
