Correct me if I'm wrong, but weren't butters/lessers first produced by Ralph Davis? And I could swear I read/heard him say that there was definitely a difference. I believe that the one who created the first morph of its kind is the only one with the right to label it or not label it as the same or different than something else.

In any case, I'm interested to hear what others may think about it. I personally think that the two are distinguishable, but I am fairly clueless when it comes to morphs.
