If Azalea and Rouge are better in some customers' minds, then why wouldn't people buy them? Also, there are serious scope differences. Someone posted about this a long time ago, but Hasbro will sell far more MP-51s than all the Rouges and Azalea variants combined. There is no excuse for MP-51 looking bizarre -- Hasbro could make her 100% cartoon accurate and it wouldn't matter if there is some other company making a 3P version that looked about the same. In fact, MP-51's strange aesthetic is only made worse by the fact that other, smaller companies are able to do much better.
