I'm not going to argue with you about the SRAM chain lasting longer than Shimano. However, I'm fairly positive that is a Shimano Chain. SRAM X01 and XX1 chains have SRAM logos on both sides of the chain. The chain pictured has no logos on it, which indicates that it must be a Shimano chain, since they intentionally only print logos on one side.
A sram quicklink is required to run a Shimano chain on Blackspire chainrings, which may be why you think this is a SRAM chain.
