With launchers you can adjust the margins, grid size and shrink/enlarge widgets. My personal preference is Nova since I like the stock Google look, but am able to adjust the grids(see how my dock has 6 spots as opposed to TW 4-5).
I'm also using minimal ui which is an icon pack that you can apply via your launchers settings.
