nova or action launcher?

Try them both. I prefer Nova and it goes in all my phones, but that's just cos I like the familiarity of it...
 
I have used Nova for years. It works well and is relatively lightweight.
 
I've used Google now launcher for a while (on my droid turbo and turbo 2) and now z force. Happened to try out nova prime yesterday and I guess I got lucky with the 5.0 update, lots of 7.1 features for app drawer, icon shortcuts, pixel search bar, etc. It didn't take long to get accustomed to nova prime either. Luckily I had 10 bucks in Google opinion rewards to help cover the $4.99 cost. Definitely worth it tho.
 
didnt like nova when i tried it a while back. been using apex launcher for a few years on a few phones and like it.
