Strange Tales #31-39: Solid sci-fi stories, even if the creative teams are largely forgotten.
Batman Incorporated Volume 1 #1-8/ Leviathan Strikes (Counting as Two Issues): Decent exploration of the theme of Batman going worldwide/ taking on new apprentices/ challenges.
Northlanders #9-10, 17-20, 29 Mostly decent shorter pieces about the Vikings.
Wolverine Manifest Destiny #1-4: Okay early Jason Aaron Wolverine project about fixing an earlier screw-up/ getting involved in a turf war.
Since I want my top ten Stan Lee stories list to be one I don't regret, I'm rereading some work that I haven't been as familiar with.
Silver Surfer: Parable #1-2: Might be Stan Lee's best "modern age" work, a collaboration with Moebius that tackles religious extremism and opportunism
Fantastic Four #82-87: A two-parter with the Inhumans has some strong visuals, but the highlight is a clash with Doom in Latveria, his best Silver Age saga, which reveals a lot about the character while tackling the issue of totalitarianism.
Journey Into Mystery #113-125/ Thor #126-130: These issues get a bit repetitive with Loki's scheming, and some sexist treatment of Jane Foster, but they do include astounding visuals and characters with staying power (Hercules, the Destroyer, the Absorbing Man.) I could definitely see why this was Marvel's third-biggest book of the 60s, after Spider-Man and the Fantastic Four.
Speaking of Spidey...
Amazing Spider-Man #24, 82: Some of the best single-issue Stan Lee stories.
Spectacular Spider-Man Magazine #2: It might be a bit padded, but the confrontation between Osborn and Peter are intense, and it is an excuse for some of the best visuals of Romita Sr's career, which means it's some of the best ever in Spidey comics. (Counting as two issues)
Peter Parker the Spectacular Spider-Man #61-71: Mantlo's second run on the title is heavily influenced by Miller's Daredevil (especially with Ed Hannigan's art), although there are some solid contributions to the mythos with Cloak and Dagger, and a somewhat incompetent Boomerang.
Spectacular Spider-Man #158-160, Web of Spider-Man #61-63, Amazing Spider-Man #326-329: The Cosmic Spider-Man saga has some flaws (the beats are repeated, some of the storytelling is melodramatic, I'm not sure I buy the characterizations of guest-starr villains) but it has an interesting crisis for Spidey (what does he do with sudden power?) as well as a litany of single issue challenges that make for an accessible crossover, where transitions between creative teams are handled smoothly.
Total So Far: 1665 Issues, 42 from the Golden Age, 29 from the 1950s, 100 from the 1960s complete, 100 from the 1970s complete, 100 from the 1980s, 100 from the 1990s complete, 100 from the 2000s complete, 100 from the 2010s complete
Best of the batch: "The Hercules Saga" from Thor. It includes some excellent challenges for Thor, and a great dynamic with Hercules, a more arrogant hero with power on Thor's level, as a rival.
