Using Adobe Illustrator, "Expand" and "Outline stroke" seem to produce the same result of converting a path to an object (correct me if i'm wrong). So I'd like to know;
- Do both commands really perform the same action?
- When to apply either command?
"Outline Stroke" is essentially a subset of "Expand". If all you have is a simple object with a stroke applied then they will do the same thing.
"Expand" on the other hand will affect most things. It will expand strokes, fills, gradients (to a single gradient mesh), blends, envelope distorts and probably more. It's bigger brother "Expand Appearance" will also expand any effects and appearance attributes applied to an object.

As for when to use each...
Apparently, according to the comments, this guy summed it up very succinctly.
