For the most part, the other cans will work. since each company has a bit of a different blend, you will get a bit different performance from the stove. I've heard that some brands don't quite follow the standard, so be sure you test new cans before a trip. But you should be fine with most brands. I've also heard that some stove-can combos require much more torque than others, so that is something to keep in mind if you get a valve that doesn't activate.
