The Cyclops of the Dark Phoenix Saga. He argues with Professor Xavier about how 'ten demerits, or ten thousand,' Wolverine is a grown man, and it takes a different style to lead him than the one Xavier used with the original teen X-Men (to which Xavier snaps that if Scott can't just boss Logan around, then maybe he made the wrong decision making Scott leader...). I love that he's right there, in Xavier's face, *defending Wolverine.* Much later, he brings Dark Phoenix down *by talking to her about how much he loves her* and ends the fight (until Xavier uses that moment to sneak attack her from behind with a mental blast, starting the fight up again and forcing a different conclusion). He's just amazing in that run.
The Cyclops of the first X-Men movie, the one who just smiled when Wolverine 'flipped him off' with his third claw, seemed very much the same sort of figure. Mature.
While I don't hate teen Cyclops, he's very much not the grown up who has earned his wisdom through experience that I want to read about. Neither are several incarnation of adult Cyclops, who were also prone to flipping out or acting authoritarian. (The Cyclops of Children's Crusade, for example, was close to the opposite of the level-headed Cyclops I prefer.)
