In Pictures: Windows 8 app shootout - ModernMix v ...
Which one is best?
The clear winner is ModernMix. RetroUI Pro misses out on two important things: the ability to pin an app to the desktop’s taskbar, and familiar function buttons on the title bar of the re-sizeable window. ModernMix is the only choice if you’re using Windows 8.1, but even if you’re not (and why wouldn’t you be since this upgrade from Windows 8 is free?), it does a nearly flawless job of letting you interact with your Windows apps as if they were regular desktop applications.
