A kiwi or OMNI can ONLY APPLY up to 50%in a 4 wheel system and maybe 33% in a 3 wheel system of their power in any given direction.

Not true.
4 wheel omni can apply anywhere from 50% to 100% of the available motor power and a killough platform can apply 66% of the available (all 4 motors) motor power.
The only advantage to crab is not having to use omni-wheels to get omnidrectional-like maneuverability, and it allows one to direct 100% of the total available motor power all the time, permitting that the crab modules are functioning and can point the wheels in that direction.
