Tie. Both had strengths and weaknesses.
Didio wanting to kill Nightwing off was stupid (he wanted to kill him because he didn’t understand the character and he admitted this in one of his monthly DC comic book blurbs which is the dumbest reason to want to kill anybody, though I swear this is what DC just did in 52…) the attempt to fix it in the comic without recalling the pages was stupid. And how Dick Grayson survived still hasn’t been explained. The bootleg fix in the TPB doesn’t work because there is still no explanation making it all just really stupid. Everything else was great, Superboy Prime murdering people was hot and so was Joker towards the end.
Civil War was great until the ending. Though I think if the book shipped on time it would of been accepted a lot better, the build up for it was too big to live up to. It really needed a major death or something big to pull it off. Would Cap’s death in the book of helped? Maybe, maybe not. It would of been done w/o Brubaker and I wouldn’t want that either.
Though I will say that the potential for great comics to come after Civil War is really great, it’s happening already starting with Cap # 25. But since it just wrapped it’s too early to judge.
IC fall out, 52 is great some weeks but not others, have to see how it wraps. OYL books that I read were all horrible except for Teen Titans. So the fall out / aftermath has not been handled as well as the Civil war fallout. But again, it’s still early for Civil War when we will be able to see the grand scope of 52 in a couple of weeks.
In closing and I can’t stress this enough, read Annihilation instead. Well perhaps not instead since it won’t have the major ramifications of the other books, but just read it, it’s still the better crossover. Every single issue delivered. They found a way to kill a major character and still give him a happy ending, perhaps not a brilliant idea but they did it and pulled it off so in the end that’s what counts. If you don’t love Nova and Ronan after reading this book something is wrong with you. I haven’t read a single Annihilation crossover book and I was still satisfied. The way this book ended was just amazing.
Oh and it was way more bloody than both CW and IC so you know where my mind is at. 
Just my 2 cents…
