I've always preferred color over black & white, being particularly fond of the xpro extremes found in slide film. Occasionally I'll pick up some B&W in an effort to become more familiar with it, but I always end up going back to color. During my latest experience, however, part of me has turned: the film was Agfa APX, 400 speed, 35mm, and the results were a rainbow of grays, classic and impressive all at once.
Those super-strong black and white tones that you love in APX 100, but with a speed boost to 400 for extra-dark or extra-fast subject. Woot, woot says I. The bigger grain is quite tasty too.
