star_rider, ammonia binders associate with ammonia to bind it into a form harmless to fish. Ammo chips, the type that go in the filter, adsorb ammonia removing it from the water entirely. The functional difference is that ammonia binders added to the water are very useful for emergencies (as OG described), shipping fish, and ammonia spikes during a fishy cycle, since the bound ammonia is still available to the bacteria. However, it seems logical that if the bond is sufficiently strong to keep the ammonia out of solution, it would be energetically less favourable to a nitrifier than free ammonia. So my unresearched hypothesis is that ammonia binders slow cycling.
The problem with ammo-chips, zeolite, and ammonia adsorbants in general is that they create an artificial low ammonia situation, which hinders nitrifier growth by removing their food. So what happens when these are exhausted? Well, ammonia spikes and the nitrifer colonies need to grow to meet the "new" ammonia source. Not much of a problem for ammonia nitrifiers really, they're pretty quick, but nitrite nitrifiers are much slower, partly because they're dependent on ammonia nitrifiers for food.
