Higher contrast ratio is best as the colours stand out better and lower pixel size is better as the image will be more crisp. Although i'm sure both those sizes you quote would be suitable for most applications.

higher the better with contrast ratio specs. Pixel pitch is fixed for different size ranges on LCD's due to their physical size and number of pixels in the resolution. More details here: http://www.tftcentral.co.uk/specs.htm
