Which of the following would you rather have above your sink /in front of a 4' wide window?

1. One nice pendant light hanging down directly above the sink.
2. Two sconces flanking the window.

Assume the style and design of the two types of light are equally nice. Is one or the other more functional? Or is this just a "six of one, half dozen of the other" type of choice? Also assume plenty of other light for other portions of the kitchen -- I'm just thinking of the sink area at this moment.

Actually, while we're on the topic, what about a bathroom sink? Lights above or lights on the side? I've always had lights above, and they seem "easier" since I do prefer a large mirror -- side lights would seem rather far away.
