I much prefer the Nova Launcher. It looks so much cleaner and I can set how many rows & columns I want on my home screen. Plus I can set "Ok Google" to launch a Google search by my voice. I also use the swipe features of Nova as shortcuts (swipe down pulls the notifications down so you don't have to reach WAY UP THERE to the top of the screen).
Completely agree. Nova is awesome. So clean. Lots of customization. Setting my own grid size is awesome. That was the first thing I installed to replace Samsung's Touch Wiz.
