The stoves that run on petrol are dirty, noisy and often only has 2 settings: volcano and burning hells.
Certainly not all of them. The Coleman Dual fuel (I have the twin burner briefcase style) is superb. Clean, nearly odourless, as controllable as a domestic gas hob and very quiet. It packs a punch of around 40,000 BTU ;)
However, I did state that the Multifuel Bulin one I have is noisy (I did say it's a "roarer") and also leaves soot when turned off.
Now bear in mind that petrol is available worldwide. Camping Gas isn't - ISTR you can't carry it on the Chunnel (I could be wrong) and you certainly can't carry it onboard an aircraft (can't carry petrol either but you can buy it literally anywhere)
Another place where petrol has a big advantage (besides purchasing) is when it's chuffin' cold outside. Petrol still works, butane & propane won't (unless you heat the canisters)
