Trangia is bombproof but very heavy and meths has less than 60% of the energy per unit weight than gas - so for a longer trip, meths is too heavy compared to petrol or gas - it's stable so the kids can learn on it though.
Coleman Peak 1 is v heavy but powerful and uses easy to get petrol - it has been good when travelling abroad (I don't have any reliability problems with the peak1).
Latest acquisitions are all gas : MSR pocket rocket and optimus crux are both tiny, effective, light (100gram stove plus 100gram gas cartridge for a day trip) they don't work well in the cold though.
The primus himalaya gas stove with preheater has phenomenal output and a preheat coil which means in the cold, you can just hold the cartridge upside down and let liguid gas flow to the burner where it vaporises and gives full output. It's heavier than the other two but very effective.

I pick and choose according to the job - if four of us are out together, we'll usually take 2 stoves so people don't have so long to wait.
