The stock launcher is actually decent. But if you like to tweak and customize then Nova is the way to go. If you want better integration with the Microsoft ecosystem, go with Arrow.
Getting the Note 8 on Monday.. really new to the whole droid thing... would you use a launcher if you were me? Which one and why?
I used Arrow when I had the Note 7 and loved it. Now that I'm not using my phone for work I'm wondering if I should still use arrow (I'm deeply in the MS Ecosystem) or something else.
