if you decide on Gnome, keep in mind there are two main paths to follow – stock Gnome (“as the developers intended”) and Gnome with extensions (ie. addons or plugins or mods) – extensions can do everything from minor aesthetic tweaks (Blur My Shell, Rounded Corners, Remove Rounded Corners) right on up to completely changing the behavior of the window manager (PaperWM, Pop Shell) – which side of that particular divide you end up on is purely personal preference
