I heard the Comedian and Minutemen ones were good (from reviews). I didn't read any of them.
I just finished Marvel's Battle of the Atom event. The four main X-Men titles (All-New X-Men, Uncanny X-Men, X-Men, Wolverine & the X-Men) crossed over to tell a cool time-travel story. X-Men from the past came to the present (main plotline of All-New X-Men), and in the event X-Men from the future come back to the present to warn of bad things (a la Days of Future Past), and to send the past X-Men back to their time.
The art design of the older characters was really cool, with old Deadpool, Jean Grey as a female Xorn, old Beast, Ice-Hulk and Ice-Wizard, Colossus with a wicked handlebar mustache, etc. The story was cool, if somewhat convoluted. I'm hoping it'll be more clear when I read all ten chapters in one go, instead of spread out (I usually re-read my comics in whole arcs before they go in long-boxes).
The only big problem was the end. Marvel has a tendency of putting too little effort in closing threads and too much effort at setting up new ones. The last event, Age of Ultron, was terrible for that (they interspersed the covers of the books they were setting up through the last issue).
But yea, I enjoyed the story, and look forward to some of the outcomes (like an All-New X-Men/Guardians of the Galaxy crossover, where teenage Jean Grey is put on trial for the deaths that she will commit as an adult as the Dark Phoenix (our past, her future).
