All out blitz on Top Cow or Wildstorm

So...I'm normally a Marvel guy with a little DC mixed in. But, since Marvel announced Marvel Now!, I've decided that I'm going to cut back my Marvel pulls drastically and all out blitz back issues of either Top Cow or Wildstorm. I haven't decided which yet, so I guess that's what I'm asking. Which should I read and what series should I read? Mind you that I've already started on The Authority and will continue to catch up on it regardless.
