Ok so this question comes in mind after dealing with multiple prototyping tools out there. Lets consider two - Balsamiq and Sketch for this discussion. Is there some agreement in saying, that the casual (sketchy?), interface design/approach of a tool like Balsamiq makes a task like Wireframing easier, vs. doing the same task in Sketch, which is more refined? Sketch's interface, though very user friendly, sometimes overwhelms you, and a sketchy wireframe tends towards getting more finesse. Agree?

* So, Is it better to focus on a single task and then wrap the whole product around that?
