Both great skis, but it depends on the skier itself. The JJ has a very short turning radius, meaning that it will be very nimble going from edge to edge, but will lose stability and feel very hooky at high speeds. If you ski slower and on flatter slopes, than go with the JJ. The Candide 3.0 has a longer radius, and will be more stable and high speeds, but will take more work to carve on slow slopes.
I have skied the 3.0 and was incredibly impressed. It is incredibly light and fun, but can still charge. It carves well, not as smooth as my standard 3.zeros, but floats significantly better.
