This question is not easy to answer because of the lack of specifity. You need to state the type of museum - then we might have a discussion. E.g. the best rice museum is in Singapore - but of course that is the only rice museum I have ever been in. However, I was, in earlier years, on the staff at the Field Museum in Chicago, and the Museum of Science in Boston (both first class museum of their type). I believe the Field to be perhaps the best in its class; the Boston Museum is excellent, but there are many that are equal or better, e.g. the Deutsches Museum in Munich.

Nonetheless, my favorite museums are often the smaller ones that one can take in in 1-3 hours and feel like you have had a really unique experience. Most people, IMO, cannot begin to comprehend a large museum like the Field or the Metropolitan - these are museums that have to be visited many many times to be fully appreciated.
