Amazing Spider-Man recently showcased two heroes taking these different journeys simultaneously in its "Beyond" storyline thanks to the return of Ben Reilly, Peter Parker's clone from the mid 1990's infamous Clone Saga. Ben's first death at the end of the Clone Saga came after he and Peter had grown into essentially being brothers. Prior to his death he had demonstrated that he was every bit a Spider-Man as Peter was. Since Ben's return, though, his characterization and relationship to Peter has swung in different directions--sometimes wildly so--at the whims of his writers, never reflecting the character he was at the time of his first death. Regardless of one's opinion of how Ben is depicted, he's really the only character that can truly serve as an inverted mirror to Peter: high while Peter is low, falling while Peter is rising.
"Beyond" runs for nineteen issues of Amazing Spider-Man from 75-93 (plus multiple ancillary issues) and was published three times a week. The story was written by a team consisting of Saladin Ahmed, Patrick Gleason, Jed MacKay, Kelly Thompson, Geoffrey Thorne, Zeb Wells, and Cody Ziglar. The three times a week schedule necessitated an art by committee situation. "Beyond" wasn't a continuation of anything from Nick Spencer's run on Amazing Spider-Man so it's a great jumping on point. Likewise it's not necessary to have read any of Ben Reilly's previous appearances; the story provides the small amount of backstory that is necessary to understand the character's history.
