I don't think there is "one best model". There are some that do perform better than others throughout the season, but the input/calculations change before each season. Thus this early into the season, eventhough it's been busy, it's hard to say which one will predict the motion of this storm the best. Plus, the fact that it's not even an organized tropical cyclone makes it all the more difficult.

Personally, I can see it becoming a TS or even a hurricane, but it's still too far out to predict movement or even landfall.
