Hickman did write Cyclops well in the closing issues of Time Runs Out and the early part of SW'2015.
If you compare SW'84 and SW'2015 in a Marvel Universe Then and Now sense, you'll find that the X-Men have a smaller role in the latter than the former, yet at the same time the Avengers also have a smaller role in 2015 than in 1984. One thing that hasn't changed, total lack of Tony Stark, but also Captain America, leader in the first comic is missing here. T'Challa has a bigger role in 2015, as does Thanos. Peter Parker has a smaller role but he's joined by Miles. It's still essentially Doom's story, but this time Reed takes Cap's place and it becomes a Reed and Doom story.
I think Hickman in HoX/PoX and DoX is simply showing his versatility and flexibility. In his run on FF, Avengers and SW and also Shield and Secret Warriors, he went for big ideas, big scale, and universe shaking things. Whereas in HoX/PoX and DoX while the ideas are still pretty big it's largely focused in one corner looking out to the rest.
Likewise in the first time, it was Hickman by himself, here he's basically put together a band, and taken on the mantle of "Head of X" i.e. lead showrunner of the X-Line which has never happened before. It's certainly a more interesting direction to go, and quite radical. We tend to think of writers like Hickman or Morrison as "auteurs" who get total license to tell their vision and that was certainly the sense when Bendis was at his apogee or when he wrote FF-Avengers-SW, but here Hickman is creating a sandbox and a lot of talented young writers are getting attention because Hickman's given them a platform. Like Gerry Duggan's Marauders, Benjamin Percy for X-Force. It's pretty rare and quite commendable. And it also fits the ethos of the X-Men which is about all mutants rather than just one guy and it's about the diversity and strength of the line and Hickman is aware that no one writer can do justice to every kind of story that has been told, can be told, and will be told with the X-Men at any time. So it's pretty great that he can do that.
But yeah, Hickman's X-Men which might be some 3-4 years (Same time as his FF and Avengers) will be his final hurrah at Marvel, and when he walks away he will have had a defining run on all three of Marvel's major teams -- Fantastic Four, Avengers, X-Men -- under his name. There probably isn't anyone else in the history of Marvel who comes close.
