I can't say much about the styling products in these lines since I haven't really experimented with them, but as far as lines with good shampoos and conditioners, I would say Jason and Elucence are both good. Well, actually I've used Elucence serum and that's wonderful as well. And although I technically haven't tried any of Giovanni's shampoos, I'll throw Giovanni in there because I haven't tried anything of theirs I didn't like (con, leave-ins, serum, straightening gel).
