Yes, always. Lower f number equals better bokeh and greater flexibility in shutter speed. It is always better.
You did not answer the two questions.

I think the answer is obvious, 1.4. But remember lower f number is wider aperture. I am no expert here, just trying to explain my understanding.
Actually, no. the better example is the question that you did not answer: "f/2 or f/16". Aperture f/2 allows three times as much light as f/16, and will have a much narrower Depth of Field than f/16. Aperture f/2 will have more indistinct background highlights (bokeh) than f/16. Aperture numbers should always be written as a fraction, because they are. 1/2 is much larger than 1/16. Aperture f/2 is much larger than aperture f/16, and aperture f/1.8 is slightly larger than aperture f/1.4.
