I think the OP is trying to start a war!
I regularly run one of my BK’s on high. Burn time is 4-6 hours on high, depending on species I load it with, or 24 - 36 hours on lowest setting. I can’t speak for others, but what I appreciate most is the RANGE of output. I can’t think of another stove that can stretch a load of wood 36 hours, or safely rip thru the same load in 6 hours. When I say “safely”, I mean I can leave the damn thing on high and leave the house, without any concerns of overfire.
This one statement makes me really doubt anything you have to say. How quick a stove burns out is a simple matter of allowable burn rate, BTU’s in the box, and efficiency. Are you really complaining that the stove can be run on a high burn setting? If you don’t want it to “burn out quick”, then turn it down, it can go 40 hours.
To the OP: Both stoves you are considering are at the top of the heap on efficiency, quality, support, and everything else anyone could want in a stove. It really comes down to cosmetics, flue configuration, etc. You really can’t go wrong with either, they are two of the most adored stoves on this forum.
