I presume you're talking about the Military Trangia set (SAT)! The civvie set is a belter, but much more expensive. (if you are looking at that one though, the Clas Ohlsen version at about a tenner is much better value, and 90% as good!)
I have both, but find the SAT is much more flexible and useful, albeit a fair bit heavier. Don't spend extra for the stainless steel version - in my humble opinion it's not worth either the extra weight or cash, the aluminium version being plenty tough enough, and it cooks better too - no hotspots on the bottom that you find with the SS set.
Despite having a totally unnecessarily large collection of stoves of all types, I find my SAT is my normal go-to stove, and always have one in the boot of my car.
