I'm betting that the Homelite XL12/SXL saws are the winners here. I believe they went 20+ years with than one. Besides the duration, there is the amount of saws produced, as well as the number of them still running.
That would be my guess too. Thirty years ago everybody cut firewood, built fence and cleared their property with those old Homelites. It was the original Farm Boss in my neck of the woods. Everybody owned one with the exception of my Dad. He bought a 361 Poulan which was a copy of the Homelite and it turned out to be a good saw too.
