I use KISS because I love using weird and different things, and this one I like, though I’ve customized the layout. In particular I hide apps from the home screen until I tap the app search, have key things in the favourites (so visible from home screen), and I use the swipe actions. Swipe up to open browser, down to open notification tray, right to open camera, left to open app search.

I like the clean home screen so I can see the wallpaper (which shows me the NASA Astronomy Picture of the Day) and the previous launcher I used had swipe actions to open apps which I really liked so that appealed to me too.
