Good/Decent Rappers from SM groups

For every group in SM, pick one of the idols from the groups that is a good/decent rapper, then those that you pick from each group, place them in first, second, third, etc.
(I am asking for a list, not a reply that is telling me SM doesn't have any rappers.)
Super Junior
Girls' Generation
SHINee
