I prefer the dragonfly if I'm going to try and cook food in the pot - it simmers really well and has a range of temperature options that are easy to get without fiddling with how much air you put in the fuel bottle. If I'm going to try and boil water at high altitude and or cold temperatures - and just boil water/melt snow, the XGK works better. In larger groups and depending ont the length of time we're out, we usually bring a Dragonfly and a XGK.
