This is a great guide, but you should include non-tiling WMs (openbox, fluxbox, compiz, etc.) in your list (even if tiling is superior).

This. Technically speaking, compiz, compton, etc are compositors, but neofetch says otherwise. My current setup uses XFCE as a backbone (purely because there's a lot of available plugins and widgets) with compiz and emerald on top. It's a bit of a mess at the moment (accidentally deleted my entire compiz config last week), so I'm not too keen on posting it.
