I have both, the Old Boy seems more substantial in the hand, I ordered a Kiribi with a leather sleeve around the outside and I'm not too fond of that, or the extended lever thingy. The Kiribi sits around looking for something to do; the butane has probably leaked out of it by now. I also had an excellent service experience at Arango when I sent a '80s vintage Pipemaster in for repair.
A bit off-topic, I now rely on Bic EZ Reach when I reach for a butane lighter. I don't worry about dropping it, requires no refills and it easily reaches into the bottom of any pipe I own without scorching the rim or my fingers. Readily available at Amazon, Wally World and other fine retailers.
