AFAIK, any of the chromogenics work fine in 1-hour machines, in the sense that you get good negatives out of them. Kodak BW400CN, though, has an orange mask, whereas Ilford XP2 Super has a very pale purple mask. This means that the Kodak prints more easily on conventional RA-4 color paper, whereas the Ilford prints more easily on B&W paper. (I don't know about the Fuji, or the now-discontinued Konica.) That said, some 1-hour machines have "B&W" settings, and I've gotten pretty good results from Ilford XP2 Super in some machines -- specifically, the Fuji Frontier system at my local Walgreens. Overall, I'd say it's a crap shoot, but you might stand a better chance of getting prints with minimal color cast from the Kodak film, but if you intend to print conventionally yourself, you'll find the Ilford a bit easier to use.
