I'd argue that strategy and tactics is where Scott is stronger, with Steve being the more charismatic and uncompromising of the two.
The deal with Scott is that he's always facing a kobayashi maru. Sometimes getting out alive, or mostly alive is the best case scenario. That's just the x-men's lot. The Avengers don't generally have to deal with that reality. It's very difficult to compare the two leadership situations because they both call for different leadership styles.
