It's not too bad - the pot handle is surprisingly effective and it's all built to the usual high level of quality - but I never found the windscreen/pot support to be terribly effective, generally requiring some foil to keep the breezes off. Unlike the full-size Trangia sets the Mini really doesn't work well in the wind.
As an almost foolproof, compact unit I like it, but the weight is a bit high given the rather slow cooking speed and need to have an additional windscreen, and I favour a dual purpose pot/mug these days. Not having used the army sets I cannot comment on them, other than to mention that bushcrafters regard them highly.
Personally I'd suggest looking into some of the alcohol stoves made for the ultralight hiking market, such as the Brasslite range, and making up a cooking set to fit your exact requirements from there. It may not be quite so neat as the Trangia models but weight and performance will be better and you will have something exactly tailored to your preferences.
