I have a Primus Omnilite Ti. I got it in large part because it's a multi-fuel stove, it will burn kerosene, diesel/JP8, avgas, white gas or butane mix gas canisters.
The multi-fuel was a big issue with me because I'm still in the reserves and when we deploy, it's difficult to take along butane-mix fuel canisters (airlift safety issues) and could be difficult if not impossible to get them in a local economy overseas, but we have use JP-8 in aircraft, generators and vehicles and diesel is available anywhere from the local economy.
Just something to consider depending on where you plan to use it.
For most camping/hunting use here in the U.S., butane-mix seem to be the cats meow these days, but they can be problematic in very cold weather.
Another thing to consider with the gas canisters is that with some, once you open them, they have to stay on the stove until they're gone. I know Primus, and I'm sure some others, make canisters that can be taken off as needed.
I would think that those canisters would interchangeable with the regular ones...
