I have a few Zymol Waxes, the entry level Carbon, Titanium that Lee mentions, as well as some of the higher end ones.
Carbon I am not a big fan, waxes that are half the price are easier on and off, and produce better looking results. The Titanuim looks nothing special looks wise but is currently on my daily drive and beading strongly after 4 months so it is durable. Over one layer of sealant it is lasting very well. Impressed.
What's your budget ? I can talk about the higher end products aswell but then we are talking over 100 quid a pot ?
Personally on a more modest budget I would looks at Swissvax Onyx as my all round choice of wax, looks great on any colour and is easy to use. If I could own just wax it would be the Onyx.
Other close alternatives at less money still would be Dodo Juice and Chemical Guys 50/50. Choices also depend on the colour of your car.
