I can understand why someone would Like CW or IC better than the other, but ultimately the quality of the story-telling was the same. IC had giant premise that couldn't possible sustained, but the attempt was good.
CW was much more focused, but when it comes down to it, Millar isn't really that good of a writer, so he couldn't handle even that. So a good writer with an impossible story verses a good premise with a sketchy writer. Same result in the end.
