This Is No Longer A City.
Annihilation, Conquest, WoK and TI ranged from pretty good to awesome. (Conquest is definitely the weakest but it's still better than a lot of Earth events, and still had some great moments).
Would Messiah Complex/Second Coming count by this definition? They didn't have a mini but they were both huge events that spanned nearly every X-book. If so then those as well.
The amount of decompression in most of the events is something which stands against a lot of them, imo at least. House of M, Fear Secret Invasion, Fear Itself. AvX and Age of Ultron so far have all dragged on for too long and had issues where not a lot of happened and suffered for it. At least in the X-overs, despite the fact they went on for 10-12 issues, there was a lot happening in all of them and they never lost their momentum. Mean while Age of Ultron is 7 issues in and Ultron hasn't appeared...
