The Camp Chef Rainer is nice as well. I have owned one in the past. At 10K BTU, It is good if you are not trying to boil large pots of water or trying to cook on low temps. It is about $100.
But I will say the Jetboil is only $170. I assure you, it is worth every penny of the extra $70. The benefit isn't in the speed of boiling, it is the ability to simmer and cook at low temperatures with extreme control.
For the youth, it allows them to cook eggs, pancakes, and similar items without burning them. I personally cook for the adults at our campouts 10+ times a year. I use whatever grill or stove is around. Therefore, I have used a wide variety of stoves. They are all very similar at higher temperatures. It is that simmer control that really sets them apart from each other.
That being said, I still carry the Jetboil Genesis and the Camp Chef Everest to every campout. The Everest is used when I am boiling large pots of water or soup. The youth patrol chuck boxes now just have the Genesis in them. We just recently removed the Colemans featured in the video.
