Besides my alcohol stove, I also have an MSR Whisperlite International. It too can use many different types of fuels.
If you are going to tour outside the US, a multi-fuel stove will give you more options. Not all fuels burn efficiently. Some burn very dirty. Keeping your multi-fuel stove (the jets) clean will be very important. It's really just part of the flexibility of having something so versitile. When you do your research. consider narrowing by multi-fuel stoves only.
Also, when you do find one you like, cook with it using different fuel types before your trip. Nothing worse than being hungry out in BFE, and not knowing if the thing will light!
