Nova Launcher Prime for the main reason being it's currently the only Launcher to support GLOBAL Badge Notifications (those little red #'s on App icons themselves like on iOS) because once you get use to having them, you just can't go without!
Nope, GO Launcher supports specific Apps and for other Apps GO needs to update to include them (which is how many Apps do it).
On the contrary, what sets the link I posted apart is that it isn't dependent on Nova supporting Apps it chooses - virtually all Apps installed on your device that produce Notification Bar updates are natively supported.
I've ben using Go Launcher for a long time now; I think it works great and has a lot of features. It's an excellent product; it just takes a long time to customize.
Holo launcher hd.
On my nexus 7 and G note.
I found I like better than nova prime and apex pro. Have jumped back and forth many times but always come back to the smooth Holo hd.
