Kona hei hei stolen didn’t break.
Ti Bontrager broke at a weld.
Lite speed road bike chain stays split, repaired by Litespeed and still working.
Litespeed mtb still going strong.
Indy fab still going strong.
Partners van Nicholas split chainstay frame replaced still going strong.
I have also had steel Kona Unit and the frame broke on that but only after 9 years of daily commuting.
I think it’s more about the design and quality of the materials and construction rather than which type of metal.
