I prefer DEP, though thats probably becuase they were one of the first metal/hardcore bands that I really got into. They've released more than one good album, the new ones is pretty decent, tho its very different to CI. They've also had 3 excellent EP's on top of that. I quite like Ion Dissonance as well, but I just find their constant all-out assault style of music to be somewhat samey and lacking in variation at times, whereas DEP really do mix it up with a broad range of styles and sounds that really make for an interesting and intriguing listen.
