I'm a huge fan of both Andre and Marcelo, subscribed to both their websites (mginaction almost since day 1), been to seminars by both where they each taught their version of the butterfly. I even asked direct questions to each one on details of their sweep.
However, as someone for the past 5 years who has used the butterfly almost exclusively for guard (I play very little closed or halfguard), I would say the purest and most effective style of butterfly is the one of Carlos Machado. The way he teaches it makes it effective for a slow, weak, broken down old man like myself...
