[MCU] Why is Vision's body less durable that Captain America's shield?

In Age of Ultron, Vision's body is composed of vibranium.

In Infinity War, Captain America has two shields, presumably also composed of vibranium from Wakanda.

Corvus Glaive pierces Vision'a body like butter, but Cap's shield is able to turn the same blade aside: why?

IIRC, Vision is an organic vibranium weave, while Cap's shield is pure vibranium.

The weave that makes up the Vision is less durable, but it is more pliable and flexible. This tradeoff was necessary to create Vision's human-like movements. He doesn't have articulated joints like an action figure, his "skin" and "muscles" move and contract and expand like actual flesh.
