Sullivans Shock vs Zoom Bloom

What is everyone's thoughts one which one works better.

I haven't used zoom bloom but I do like shock. It's not a miracle product, like always you have to work on the hair regularly to get good results.

Maybe I just haven't learned to use Shock yet, or maybe I'm just old school, but I feel like I get better results with Zoom Bloom.  I just seem to get as much pop and more shine with it. The key with it (and probably the other too) is to blow it in, then keep blowing it for a long time, and then blow it in some more.  Like shortii says, nothing works it's best if your hair isn't healthy and working to start with.
