I've been using NXT for about 6 months now and am very pleased with it. Other products I've used include S100 Carnauba, Meguiars #26, Meguiars #20, Meguiars Gold Class and Zaino Z5/Z2. I've also compared it to Souveran Carnauba. It may not protect as long as #20, or darken the finish as much as Gold Class and may not be quite as deep as Souveran (very close), but it does offer the best metallic pop of all the products I've tried and I appreciate it's easy on easy off with no dust application.
As ntwrkguy already mentioned, the key to a beautiful finish isn't the coat of wax used, it's the polishing and preparation of the paint before the wax is applied. Then it just becomes a matter of personal preference.
