Based purely on 'wetness' alone, Natty's Blue is the wettest looking wax I have used. That doesn't mean it will look the best on all colors. Like S100/P21S and Collinite 845, it tends to look a little too bright on solid dark colors for my tastes. I prefer to use it on metallics and solid light colors for that reason.
The two that give me the best balance between wetness and depth on solid dark colors is Clearkote's Carnauba Moose and Pinnacle Souveran.
