Back when I was a product manager, no small part of my job seemed to consist of making a decision--ANY decision--so that things could proceed. Often it fairly obviously didn't matter and, even if it somewhat did, there was often no clear way to inform an optimum answer. (Of course, sometimes there was--but it was probably the minority of the time.)
Also, a prompt decision can also get the team to the point where the decision is proven wrong and one of the other decisions correct or, as is often the case, a separate best option becomes obvious.
