Zymol makes some good products, but if you have prepped the surface well enough, you won't really get your money's worth in results from the wax alone. You can get amazing results with a $15 wax like S100 if you've done the prep work.
I would break down the aesthetics of detailing as:
75% Polish/Clay/Shampoo (gives you the smoothness and shine)
10% Glaze (adds depth and masks minor swirls)
15% Wax (some waxes add more depth and can increase the shine/reflectivity of the surface)
Most people think that wax is what makes a show car, but the wax is mainly there for protection and is just icing on the cake.
I guess what I'm trying to say is save your money and buy more cost-efficient products
