I say IBM is the winner here. IBM 7030 Stretch gave IBM a design based 
on 8 bit bytes, that followed with the IBM 360. Salesman love bytes 
because now your 4K of memory (36/48 bits) is  32KB of IBM memory and 
time sharing because you can FAKE the need for real memory.
Ben Fan of 36 bits but not the PDP 10.
