I've tried a few on mine over the years and my two favourites are:
Clearkote Carnauba Mousse Wax - relatively cheapish wax, very wet look, decent durability, so easy to apply.
Swissvax Best of Show - quite similar to above but more expensive and excellent beading. Very easy to apply and smells great.
As already said, most of the looks come from the prep work - paint correction or at least a good cleaner / filler polish.
My car is garaged and only occasionally used. For durability and looks I would go for Collinite 845. I use this on my company car which stands outside all the time and covers decent mileage. Colli 845 gives superb beading and very good durability even in winter.
