I personally use Meguiars Liquid Cleaner-Wax. What any wax be it paste or liquid does is remove a thin layer of material off of the surface and then harden into a new layer of protection. In a perfect world, the material you clean off would be old wax, but in the days of less time and more acid rain, the material tends to be your clear coat. Don't worry, it would take you decades to wear through the clear coat.

My long winded point is use what ever is easiest for you. The main thing is to do it often. Paste wax used to build up, but with the harder clear coats, the wax today has more abrasives in it and will remove the old wax (if nature doesn't).

I went for two years without waxing my car do to laziness and other mental instabilities (no comments from the peanut gallery) and when I finally did, It made so little improvement, that I had to wax it every other week since to return it to a decent finish.
