I don't like the stock launcher because I can't remove the search bar and I never use the search bar. Nova feels like a no nonsense launcher that does what I need. I think last time it came up, the recommended option was missing something for me so I stayed with Nova, but the writing is on the wall.

Checked again and I don't see a way to get a button to show the app drawer on Lawnchair, and I don't want to use a gesture, so that's going to be hard to use.

For me the advantage of nova is increasing the density of app icons able to be displayed on the home screen and app drawer.

I run with a 9x7 home screen grid and 8x6 app drawer.

This allows me to have a weather widget with a large clock and an excellent calendar widget called Todo Agenda displayed while still allowing me to have all my apps accessible on one screen.
