After trying Zymol (not at all impressed), Zaino (didn't like the look) and half a dozen other waxes I still prefer the Megs Gold Class. Zymol carbon was by far the biggest dissapointment of all waxes I've ever used, it's all about marketing hype.
jcd,
If you want a super slick and even higher reflection/shine try Meguiars Final Detail (Not Final Inspection or Quick Detail). You can buy it from paint supply shops for $18/Gallon, I am willing to bet you would be more impressed with it. The best part is that after using it a couple of times it builds a super slick layer on your paint which makes it easier to remove any future dirt (as long as it doesn't rain) I even have trouble getting the blue painters tape to stick to my paint.
