My opinion... It's the same mutation. There are a lot of different genes at work making up an individual 'look'. Anything from the shade of yellow in the background color to to the distribution of melanin in the pattern, to how many alien head patterns make up the sides. These 'extras' may have a an effect on the overall look of the individual, but they don't have any effect on the specific mutation. So I say, get whichever one is cheaper and breed it to a superior example of whatever has the overall look that is most pleasing to you.,
