As long as the currency is widely used, and if it does not require that I carry around large quantities of paper or valuable metal/minerals, I don't care. It seems to me that our current monetary system (mostly electronic) is just as practical as most sci-fi systems, and far superior to any fantasy system which still uses lots of valuable metals carried around in bags, just waiting to be stolen in The Shades or some other part of a fantasy universe with a particular high density of alleyways.
For the rest, this is just a popularity contest between different fantasy/scifi universes, isn't it? I vote for the Discworld.
