I don't think these are very comparable to the Quest Pro.
It appears neither of those have face tracking, and the Pimax doesn't have eye tracking. Besides that, both of those are PCVR (not standalone) and the Aero doesn't even come with controllers despite costing nearly $2000.
Could you name the other more advanced standalone options? I'm only aware of Pico, which is near parity, but tied to the CCP.
