I've tried 4 or 5 different launchers I think and some of them are ok but they're obviously coming from an Android mindset or possibly trying to emulate iOS. As such they're just 'wrong'. Both Android and iOS have years and years of built up UI cruft which is ironic given the Symbian UI they were displacing back when they launched.

A Swipe UI on Android without rooting the device is much preferred as my main handset has a couple of apps I rely on that will not run on a rooted device - banks are picky like that.

And then you've got the Android apps to replace as it's jarring to go from a swipey launcher to an app that relies on button bars, burger menus and floating action buttons though perhaps the latter isn't a bad idea for a swipe based UI.

It's a pity we've not got Silica components on top of Android for some rapid ports of apps.
