I have no clue how you're drawing that conclusion. The lightning connector is indisputably more durable than USB-C and failures of lightning ports outside of extreme abuse is pretty much unheard of.

I think people argue this because the little pins for lightning are in your device. If these break there’s no fix. The flexible pins on USBC is in the cable. Do if the pins break, you get a new cable. Thought arguably, you now have this thin plastic flappy bit. But none of the parts that are meant to flex are in your device.
