Well newbie, if you come back, the best and has the hottest flame is the Coleman Xpert, Xtreme stoves. Jim Shaw has the two burner version which I think is the Xpert, I picked up a single burner Xtreme a little over a month ago, they unfortunately use discontinued Coleman Powermax canisters which are hard to find now and expensive. I put in a supply of about 10 bottles now. Most stoves, I can hold my hand over them about a foot to a foot and a half and the Xtreme about 2 feet above the burner. When I met up with Jim last Labor Day, he brought along his stove for our overnight trip. I was very impressed with its speed boiling water.
