In general, the SysML DirectedFeature approach is more powerful and the notation is cleaner than UML provided/required Interfaces. Prefer SysML DirectedFeatures unless you have a really good reason to use Interfaces!
Provided/required Interface "lollipop" and "socket" (a.k.a. ball-and-socket) notation can quickly lead to clutter in UML Composite Structure Diagrams and SysML Internal Block Diagrams. SysML provided/required DirectedFeature notation is cleaner.
