I definitely choose the snail ! First of all, because I'm biased and I love them. Secondly, its colors are much more cheerful, and here and there it shines very nicely. There are much more patterns on it. These are all appreciated. Let's say more popular traits. Another argument in favor of snail is that it is a much better known creature than the armadillo. I have observed that it is not worth putting complex or interpretative works in competition, because there is little time for this level of perception.
