I grew up in a house heated by 2 different blaze king wood stoves (my grandfather used to sell them). We also had hot water circulator coils in ours. While I can't compare them to other brands, I can say that they lasted for at least 20 years of heavy usage and never had a problem. And they were certainly more efficient than a stove without a catalyst.
One thing I do remember however, is the frequent chimney cleanings. Our catalysts had a lever to bypass them for starting the fire. Once the fire was going, you close the lever to force the smoke through the catalyst. Because of its design, creosote tended to collect on top of the catalyst and eventually prevented the lever from fully closing. We had to open up the chimney and remove the creosote 3 or 4 times each winter. Not terribly inconvenient, but more frequent than the annual cleaning I do on my current wood furnace.
