The Primus Omnifuel Stove is very flexible in what fuels can be used, probably the most flexible in the world as it can use propane/butane gas resealable gas cartridges as well as white gas. It will also burn diesel, petrol and even kerosene (these are really not recommended though because of the toxicity but sometimes needs must) and has an adjustable flame. You can even get one made from Titanium. One of the main criticisms of the MSR multifuel models is the plastic pressurization pump.

If your looking for a purely gas cartridge stove the Optimus Crux is really neat because of how compact the stove is.
