No contest, the Trangia wins. The MSR is a good stove, quick to light, high
output, but very expensive to use, OK on a day trip.
The Trangia lights quick, very good output (loves windy weather), is dirt
cheap to run, and will last a lifetime; no moving parts to go wrong, no jets
to clog.
As for weight, by the time you have packed a pan or two for the MSR, there
is not a lot of difference between the two.
I like gas stoves for what they are, a quick solution when you need a hot
drink or quick noodles, I hate the idiots who leave empty gas cans all over
the countryside (any empty cans / wrappers for that matter).
