I've been REALLY pleased w/ Kodak Portra 400 for color. Good saturations but still yields very natural skin tones. It works in several different lighting situations and can be underexposed 2 stops easily. I've shot some indoor stuff under fluorescent lighting and the result was very pleasing.
Kodak is releasing the new Portra 160 soon which is sure to be a FAVORITE for everyone. If it's anything like the 400, every film wedding photographer will be shooting it.
For b/w, I've really liked HP5. The choices are seriously limitless. Experiment and find the look you love.
