Just five is real tough as I'm loving a lot of Marvel titles right now but I'd go with:
5. Wolverine & The X-Men - AvX has derailed the book momentarily but prior to being sucked into tie-ins (which have been fine, but they've just interuppted the previous flow of the book), W&TXM was pure comic book heaven. AvX is fine and all but here's hoping that Aaron and co. can get back to their own thing once it's done.
4. Venom - This book has been brilliant from the start, basically presenting the early years of Peter Parker's crimefighting career as through a very dark and warped mirror. Like early Lee/Ditko Spidey, Flash is trying to juggle a love life with Betty Brant while keeping his heroic ID a secret. And, like those early Spidey's, each issue usually ends with Flash brooding in solitude over his myriad of troubles - which only seem to mount each issue. Unlike Peter, though, Flash's problems are a whole lot more intense than not getting Aunt May her medicine in time.
3. Winter Solider - I hope this title can continue for a long, long time as it's outstanding. Brubaker's Cap run is trickling to an end but he's on fire with this book. Like Brubaker's best work, it has impeccable pulp flavor and a welcome sense of grit.
2. Daredevil - all the accolades are completely deserved. DD has had more than its share of great talent and classic runs so it's saying something to say that Waid and co. are making this book as good or better than it's ever been.
1. Amazing Spider-Man - just so consistently good and Slott fits so much storytelling into each issue. Even moreso than the outstanding Daredevil, this is the model of what superhero comics should be.
