I had a German friend who used a Trangia type stove, was the first time I had ever seen them, even from camping and canoe camping as a kid and teenager with groups (who knows, maybe they were used, but they didnt register with me)

Seeing my friends alcohol stove, as I had a new (then) Whisperlite, which I didnt really find that noisy, I never considered changing simply cuz I had a stove that worked.
