Someone on FB was asking about chains,

I had to dig through my old receipts for the info I installed an EK 530ZVX3 its tensile psi is 11,100psi
based on that alone compared to a D.I.D. which is 10,400, and 8 542.7 for a Tsubaki, its my choice.

I dont know >if< it lasts longer.  Maybe someone will find this useful....
