There is virtually no canon on the Marauders school years. We know that McGonagall said the James and Sirius were virtually Pete and Repete with Peter Pettigrew as a tag along. Also, that James and Sirius were at or near the top of all classes seemingly without needing to work at it. Remus had a very big secret to conceal which he seems to have done successfully from most. So he must have made an effort to be inconspicuous in school. Also, he was a prefect so we can infer good grades and a sense of appropriate behavior. He said that he didn't try hard enough to put a stop to his friends mischief but Remus was extremely grateful to them for friendship and the Animagus project. Most Marauder fans take it to mean that Remus was sneakier. More of a stealth Marauder and perhaps even the planner or researcher of the group.....
One of the few things canon does give us is that it took 2 large animals, the stag and the dog to keep the wolf in check and that they were mostly successful with a couple of near disasters! So I'd say the wolf was the Alpha in that pack! The other thing that we have from canon is that in OotP, when Lupin said, "Sit!" Sirius complied immediately!
