I'm sure swapping to allen-head makes stripping far more likely.
Allen-head is basically inferior (and used mainly for cosmetic reasons or to restrict screw/plug head-size) because the key-head must apply the loosening torque using a very small distance-measurement. (Torque = force x distance). This means the forces applied to the female hexes by the allen key head (in the socket) have to be far greater (than if a traditional socket were being used on a hex-head) with much less metal-contact there to work with.
In applications where high loosening-torque needs to be applied, Allen-head only work satisfactorily if the metallurgy in the head and key are top notch.

I agree with that. I think the ultimate would be a Torx-plus socket head.
