jaimeb82,
To add to what Chazzy said, the choice of the film has to be based on the subject matter, both for black & white and color. I find Kodak NC and VC excellent for portraits, wedding, and photographs where the facial colors are important. I use Kodak UC 400 [carefully stored away in my freezer to keep it from the hoarders] for red rock when I am shooting landscapes. Ektar will probably be my color film of choice for landscapes when my supply of UC runs out.
