Convenient processing, if you are not inclined to do it yourself, fine grain for a 400 speed film, nice tonal range, good tolerance to massive overexposure, are all good reasons to use XP2 Super. C-41 films also scan much better than conventional B&W materials should you choose to go that route. But they do have a much different look when printed on conventional B&W papers. It's not bad, just different.
