I have never cared for Secret Avengers, it's by far my least favorite Avengers title. I didn't care for Avengers Academy at first but it's pretty good now.
Spider-Island was a great Spider-Man epic. I even liked the tie-ins for the most part! I've been enjoying ASM more since the "Big Time" arc.
I liked X-Men Schism. The X-Men needed a shake-up... I liked the creation of Utopia with the Dark Avengers crossover but not really anything since then.
