It may be argued that the Primus 71 was better than a Svea (putting aside the self-cleaning model), because while its weight and bulk were comparable, its larger tank capacity enabled the user to go longer without needing a separate fuel bottle.

There are probably similar discussions about the Ford Mustang vs the Mercury Cougar.

I purchased the Primus 71 ($12) merely because it was the only immediately available stove but more typically, Optimus was the only brand you could get from the big suppliers during a certain time period in the U.S.
