I dig this stove, and it's the one I always turn to (I also have a Primus Multi-fuel). I like it because it's efficient, quick, and super easy. You can carry it around, use it in your tent (or your vestibule), hang it, and you don't need to worry about balancing a pot on some tiny stove. And if you absolutely need to use a bigger pot, you can.
That said, it's not for everyone or every situation. If you're cooking for a big group of people, want to do something gourmet - simmering, making perfect food, or if you can't find (or hate) canisters, you might want to look at something different.
