Rather than a tale featuring Spider-Man and Daredevil together, this just collects a three issue Spider-Man tale and a three issue Daredevil one. I enjoyed the Spider-Man one more, but I tend to enjoy Spider-Man comics more than I enjoy Daredevil ones, so that's not terribly surprising. I can understand the frustration other reviewers feel at Spider-Man being somewhat childish at times, but I found that despite that, he was also shown as a competent leader, which is not a role he normally fills, and showcased his heart in a very gritty setting (for Spider-Man).
The Daredevil stories were different. It showed Daredevil grappling with the philosophical and theological implications of his wielding the power of Heimdall, and what that meant in regards to his Catholic beliefs (including a flashback of him being mad at Thor for calling himself a god upon their first meeting). I found that kind of inconsistent, but at least an interesting thought experiment. The art in this one took me out of it a bit, though, because it featured some very awkward flips with a sword that looked like bad animation in a video game, and not any natural way one might hold a sword while flipping. Kingpin looked pretty weird at times, as well, but it wasn't completely awful, just maybe in need of a bit of refinement.
As War of the Realms tie-ins go, this was above average, and I enjoyed it.
