Do you shy away from answering questions that begin "What's the best..."?

I find them impossible to answer because they imply both a knowledge of all the possibilities and the judgment to rank-order them fairly. Typically there’s no mention of criteria, either.

Instead I’d be happy to answer “What’s a good…?” or “What are some of the best…?” but these questions are hardly ever phrased that way.

Am I reading too much into these questions? Maybe the person isn’t really looking for the one and only best product of its type or best way to do something but just one that’s worth recommending.
