It's not rocket (jet) science
The main stove beginning with J may boil water 40secs faster but is it really worth paying an extra £120 for those 40secs? These are built on a simple principle, we're not talking about a comes piece of kit here, and quite frankly even if it stopped working after a few trips (which I can't see how or why) just buy a new one! There is nothing wrong with this stove , but if your snobbery requires you to pay over the odds, then go ahead, buy the other one. Personally, I'd rather put the money saved towards a better tent or better pair of shoes, i.e., towards somewhere it would really count.
