Of those who have used both which do you prefer on your NotePro: the Nova Launcher or the built-in TouchWiz?
Personal preference really. The beauty of custom launchers is more control of widgets and grid size and spacing. The downside is that you lose some of the samsung widgets and the magazine UI. For many of us that isn't a con though.
Custom grid spacing, the resizing of widgets, overlapping of widgets, placement at half grid spacing, full margin control, disabling of widget margins (padding) and addition of gesture support for both desktop gestures and icon gestures are some of the reasons why I can't live without Nova Launcher.
