Hey anon! I was asked almost this exact same question a few months ago, so I hope you don't mind a C&P job!CREATIVE TEAMS:- Stan Lee/Steve Ditko, Amazing Spider-Man 1-40(Honestly, ASM from Lee to Owlsley is an almost unbroken chain of awesome with the major exception of Denny O’Neil - seriously, I don’t even know what happened there.)- Roger Stern/John Romita Jr, ASM #224-252, more or less- J. Michael Straczynski/John Romita Jr, ASM vol II #30-59 and ASM vol I #500-508- Peter David/Rich Buckler, Spectacular Spider-Man #103-126 roughly, doesn’t really pick up until #107- Paul Jenkins/Mark Buckingham, Peter Parker: Spider-Man vol II #20-57- Kurt Busiek/Pat Oliffe, Untold Tales of Spider-Man #1-25 plus annualsSTORY ARCS, MINIS, SINGLE ISSUES:- Death of Gwen Stacy, ASM 121-122- Nothing Can Stop the Juggernaut, ASM 229-230- MJ's character development arc, ASM ASM 256-261- The Commuter Cometh!, ASM 267- Gang War, ASM 284-287- The Death of Jean DeWolff, SSM 107-110- Eye Witness!, SSM 121- Kraven’s Last Hunt, (cross-title arc, see here)- Revenge of the Green Goblin, (mini + cross-title arc, see here)- A Death in the Family/Return of the Goblin, PP:SM vol II #44-47- Spider-Man: Blue (miniseries)- Spider-Man/Human Torch (miniseries)- Spider-Man: Fever (miniseries)- Parallel Lives (short graphic novel, reprinted in You Just Hit the Jackpot)This is a somewhat eclectic combination of "stories I think every Spidey fan should read" and "stories I really, really like," with the result that there are probably some stupefyingly obvious candidates in both categories that I've overlooked.You asked about ASM specifically, but I included some other storylines, and I've written a bit about my favorite Spectacular Spider-Man storylines here. You can also just bookmark my recs tag for future reference. Hope this helps!
