We have used Kohler Biscuit (and Toto's matching Sedona Beige) because White is too cool/stark in our bathrooms{{gwi:807}}. Biscuit is a creamy off-white that is not as dark as almond. It has a warmer look and many (probably most!) people do prefer the crisp look of true white. It really depends on the look you're going for and the color of the tile and other elements that you'll have in the room. With so many shades of white out there, I wouldn't commit to the tub color until you've chosen your tile.

If you're doing a true white subway tile you should do a white tub, IMO. I think the contrast between the tub and any other color would make the tub look dirty. I don't think there is any advantage to the other colors.
