The big advantage to the C41 BW films is their incredible exposure latitude. Most of it can be shot from ISO 50 to 800 with no change in development.
Have you seen the Kodak Gold 800 (C41 color) commercial where the family is out on the beach in the bright sun taking pics, and then later, just as the sun has set they are out on the beach again taking pics in the dark? Kodak is trying to push Gold 800 as the all-purpose magical film; it's magical alright, cursed, the pics suck no matter what the light.
Anyway, these C41 BW films can pull that off; they're the magic film. Shoot it in the sun at 100 or 200, and then walk inside and shoot it at 400 or 800 on the same roll. No special dev instructions necessary; just drop it off at the lab as usual. I like it for when I don't know what the lighting is going to be; it can be very all-purpose.
My only problem with it has been the contrast issue as Tyjax mentioned. But I think this only happens when you're trying to print on traditional BW paper from the film designed for printing on color paper. The orange base makes it tough.
