Agree with Gustavo's points on scanning. Colour negatives can produce excellent scans.
Colour negative scanning entails some more work. Hardly will a good scan come right out of the first scan.
The orange mask (not really the film base since a colour negative film has a CLEAR base) is really a weak yellow/magenta positive which develops whereever there is no negative image which a good scanning software is able to sort out properly. The mask itself should not create problems.
In the days when colour negatives were still printed optically on chromogenic paper, it took a lot of effort to balance the colour and contrast values. A lot of corrective filtration was done to get this balance right. The filtration essentially corrects the defects which uncorrected light will make when it passes through the negative's less than perfect colour dye set. The scanner is not going to be different in this case. The first output scan will tend to look flat or even off-coloured as it comes out. To really make the scan snap, correction has to be done after scanning.
The colour negative can contain more and better information than a colour positive when it comes to producing digital images. Colour negatives have more potential when it comes to recording the highlight and shadow details than a positive slide. Getting most of these potential information on the scan will tend to make the negative scans look flat. During the tweak, the operator is allowed to decide which to keep and which to discard, how the contrast, hue, and saturation will be, and to some extent even the dynamic range.
Colour negatives are also easier to use- exposures need not be perfect all the time to produce good positives, and these films cost less than slide films. The colour slide/chrome film world is rapidly decreasing- becoming less accessible, less available, and more costly than colour negative stocks.
