For light weight the Jetboil is excellent - the Jetboil itself is fairly light and you save a significant amount of weight because it's a lot more efficient than traditional gas stoves so you need carry significantly less gas, it's also fairly easy to shield it from the wind. The Jetboil does have limited versatility but with a lot of ingenuity that can be overcome.
With cooking equipment there's generally a trade-off between weight and versatility. If you sacrifice the need to fry things that reduces weight significantly.
