So sneaking passed a guard is opposed but an arm wrestle is competitive?

Why? What's the criteria?You can't get more opposed than arm wrestling.

It's a matter of perspective and degrees.

Armwrestling could certainly be a simple single opposed check. One roll and boom you're done. However, the dramatic feel, and the tension of a significant arm-wrestling match can be better displayed as a competitive match. You can see the ebb and flow of it before someone wins. You get the feeling and story of the back and forth process of the armwrestling match from treating it as competitive. Compared to that, an opposed check would be rather flat.
