I use a homemade beer can stove ( the stove is homemade, not the beer

) 10g and is basically using something that would normally get thrown away. I use it with an Alpkit 650ml mug and a windshield made from some aluminium foil I had lying around, possibly <cough> from an old disposable barbeque</cough>. Everything (plus lighter, lint, tea bags and porridge for the morning ) fits into the mug. So really just a very compact version of the Trangia.
Gas is convenient but you've the weight and bulk of the canister to consider, also unless you refill the canister then that's just waste.
Petrol stoves are probably overkill for bikepacking unless you are in the Arctic where their greater heat output is ideal for melting snow and getting things going.
