I really like the simple, stock - ish layout on my home screen, which rules out a few popular suggestions like Niagara.
I liked Lawnchair, but development is dead. Even the new alpha hasn't been updated in a year or more, and is missing features.
Neo Launcher perhaps came close to being the most ideal, but it is buggy as hell and also hasn't been updated in a year
Nova is what I'm using now, but I hate that it does not remember the drawer groups for each app once they're reinstalled. I work as an app tester and having to sort work apps manually every time drives me up the wall
