I'm hesitant to say that kips are superior to chins; I simply don't know enough to address this question. But kipping chins have been used for a long time, as have "strict" chins. The kipping chinup is a dynamic, full-body movement that contributes to the development of power and speed. Strict chins focus more of the force on the lats (and to a substantial degree from abdominal and bicep assistance), and are more of a body-building exercise in the truest sense of that word, in that they are used specifically to produce a stimulus for growth (in the lats).
There are lots of movements that exist as dynamic and strict movements; for example squats and jump squats.
Both types of movements "work". They just don't do the same thing. It would be like comparing a 20 minute walk with a 20 second sprint. Sprinting isn't the cheater version of walking. They're both good, and they both "work".
I don't know if I can speak for everyone else, but my problem with kipping pullups was simply that they were suggested to the OP as an exercise, even though he's looking for lat-development.
I agree that, just like many other exercises, there are dynamic variations for speed, power, agility, etc. However, in the context of bodybuilding and strength, strict movements are ideal. Of course, incorporating some staple dynamic lifts like hang cleans is a good idea, but I would never replace a staple strict bodybuilding lift like pullups for a momentum lift. Hang cleans I find more suitable in a strength program since (a) unless the lifter is following a program with power/dynamic sessions, cleans are often the only power lift in the program, and (b) the only strict compound a hang clean would usually replace is the vertical push, so a military press or shoulder press, etc. And, of all the six planes of motion I feel vertical push is the only expendable one, as horizontal push will cover the same muscles in addition to pecs.
