Favorite pre-Secret Wars Marvel comic… of the past 70-odd years? That’s a tough one, but I’m tempted to say Steve Englehart and Al Milgrom’s West Coast Avengers. If you mean immediately prior, then G. Willow Wilson, Adrian Alphona and team’s Ms. Marvel.
The one I’m most looking forward to after Secret Wars? Either New Avengers or Ultimates, because I love Al Ewing’s work. Unsure about either of the art teams on the books, but (a) willing to be proven wrong, and (b) it’s a Marvel book, so chances are the artists on the first issues won’t be there by #7 anyway.
