Over the course of a year I tested more than 30 stoves for a review in Overland Journal, I believe it was in our 2014 Gear Guide. Within the category of two-burners, I tested roughly 7-8 stoves. All of them from Primus, Camp Chef, and even a few other no name dogs, did relatively the same. The Primus had the better overall construction of the mid-range stoves.
Partner won our Editor's Choice award for only a couple reasons. First, it is the easiest to hard mount to a slide out system as many overlanders like to do. It also had the most robust construction. I think if you were rafting, which many Partner owners do, that extra brawn is worth having. However, the new Colemans with the new FyreChampion burners were extremely good. I think the Coleman is the better cooking stove....by far. That burner technology really does work and the simmer control is superb.
I didn't expect the Coleman to do well for no good reason. I was surprised it rivaled the Partner, even bested it in some regards.
BTW, the new Eureka stove uses the exact same burners as the new Jetboil Genesis. I would still recommend the Coleman.
