Danny Rand's run as a solo hero lasted 15 issues. 26 if you count the stint headlining Marvel Premiere. Luke Cage did better. His solo run went 49 issues, first as Luke Cage Hero-for-Hire, then as Luke Cage: Power Man. At the end of the day, neither was apparently doing well enough on their own. So somebody got the idea to do a team-up book between the naive kung fu white boy and the street savvy black guy with bulletproof skin.
Power Man and Iron Fist took over Luke's book's numbering at issue 50, and ran to issue 125, at which point, Danny got killed. (John Byrne later reversed this in his Namor run, of all things.) I bought 21 issues a few years back, whichever sounded interesting to me. Most are written by either Mary Jo Duffy (from around issue 58 to 80), or Jim Owsley (from the last year of the book). Mark Bright drew all the Owsley issues I've got, while Duffy's are drawn by, variously, Trevor von Eeden, Marie Severin (with Steve Leialoha), Kerry Gammill, or Denys Cowan. There's also a 4 issue story by Kurt Busiek and Ernie Chan in the mix that concludes at #100.
Maybe it's just the issues I picked, but it feels like the book makes more use of Danny's supporting cast than Luke's. Colleen Wing and Misty Knight are around a lot, either hanging out with Danny or on jobs of their own (which inevitably dovetail with whatever Luke and Danny are doing.) Danny's corporate associate Jeryn Hogarth sometimes gets the boys jobs.
They do operate out of Luke's set-up in an old theater, so his pal D.W. is around a lot, and there's some time spent on Luke's various romantic entanglements. Plus, the book is using Luke's "hero for hire" storytelling engine. Maybe incorporating more of Danny's cast and villains was a way of balancing things. Plus, you can get some mileage out of throwing Luke Cage into mystic cities, fighting spectral ninja assassins and sentient, angry plant-people.
And it's in a different way from putting Danny in a world Luke is accustomed to. Danny's utility in those stories is his naivete (and probably the fact he doesn't look intimidating at first glance.) Like when Danny is hired by a woman to protect her from a stalker that turns out to be Whirlwind. Even though the man is a costumed criminal, no one in the neighborhood will help Danny actually find him. Because Whirlwind is from there, and Danny's not, and he can't navigate the idea that matters more than the man being a crook.
With Luke in K'un-Lun, it's not him being naive, but him seeing things with fresh eyes. Danny, even if he doesn't agree with all of it, is used to how things work. He doesn't object when women are treated as irrelevant, and leads the charge to try and exterminate the Hylthri. When Luke questions him about it, Danny says that's just the way things are here. Luke gets to act as the one who cuts through the pomp and the bullshit and get things moving. Plus, Luke and Lei Kung the Thunderer make an interesting duo, mutual (grudging) respect masked by irritation on Luke's end and condescension on Lei Kung's.
In between stories about power struggles over an other-dimensional city, or assassins trying and start a nuclear war, there are more lighthearted stories. All the writers get mileage from Luke and Danny taking jobs they find distasteful and demeaning, or simply being caught up in bizarre circumstances. One time, Luke may come into possession of a quarter that's actually a device that disrupts electronic circuitry, and gets hounded by some crazy mountain climber whose associates look like Sydney Greenstreet, Peter Lorre and Humphrey Bogart. Or they take a job to check on some vault in the Alaskan tundra, which turns out to be empty for some reason, and the security guard, already loopy from the isolation, goes completely round the bend.
