Both of these start fresh after Heroes Reborn (I loved Heroes Reborn ). This is the first time the titles re-started with #1s and nothing really noteworthy happened in these collections. I would save my money.
When they re-started with #1s I got Amazing Spider-Man, Peter Parker, Fantastic Four and Thor. Waid's Captain America was good. Avengers had a pretty good Ultron arc didn't it?
