OTK equivalent axle brands

Are the OTK copy axles like swift, prodezine, gmax similar enough to the OTK stiffness grade to warrant consideration?

Definitely curious to see what the experts think of this one! I didn’t know there’s were copies of OTK axles.

I’ve used the Swift CRG replica axles in the past because oem CRG axles are $$$. Very similar in my experience, I assume the OTK would be the same. But oem OTK axles are just about the same price as the copies…
